The first Medify unit I set up was an MA-40 in a living room that backed onto a busy street, and the thing that struck me wasn't the airflow — it was how little the box told me about what was actually happening inside the room. No number on the display, no app ping, just a fan and a filter doing their job quietly in the corner. That's the Medify experience in a sentence: serious filtration hardware wrapped around almost no digital feedback, at a price that undercuts most of the True HEPA competition.
Medify Air, LLC has built its entire identity around one claim: hospital-grade H13 (and now H14) HEPA filtration at a fraction of what brands like Alen or IQAir charge for similar media. The lineup has grown from a handful of desktop units into eleven-plus models, from a 470-square-foot tabletop unit up to a commercial tower rated for spaces measured in thousands of square feet. What hasn't grown at the same pace is the smart-feature set — most Medify units still ship with a fan, a filter, and a timer, nothing more.
This guide walks through every model Medify currently sells, tier by tier, with real coverage numbers rather than marketing square footage. It also covers the part most brand guides skip entirely: what a Medify filter actually costs you over a year compared to the competition, and a warranty condition that drew a formal compliance warning from the FTC. If you're trying to figure out whether a Medify purifier is the right long-term fit for your room — not just your budget — this is the full picture.
Medify's Philosophy — Medical-Grade Filtration, Minimal Frills
Medify Air, LLC is a Florida company, headquartered in Boca Raton, that has positioned itself squarely on filtration credentials rather than smart-home appeal. Every current model runs a 3-stage design — pre-filter, True HEPA H13 (or H14 on select units), and activated carbon — and Medify leans hard on the H13/H14 distinction in its marketing, since H14 media captures a finer particle range than the H13 standard used across most of the mid-tier lineup.
What you won't find on most Medify units is anything resembling a smart ecosystem. Outside of the MA-15 SMART, which adds Wi-Fi and Alexa voice control, the rest of the current range runs on physical touch panels: fan speed, sleep mode, a timer, and a filter-change indicator. There's no onboard air-quality sensor and no auto mode on the MA-40, MA-50, or MA-112 — a deliberate simplification that keeps unit prices down but also means the purifier can't respond to a spike in smoke or dust on its own. If real-time air-quality feedback matters to you, it's worth comparing against a Levoit or Winix model with a built-in laser PM2.5 sensor before committing.
Older Medify units — the MA-18, the original MA-Smart, and the higher-capacity MA-125 — have effectively been folded out of the brand's featured lineup in favor of the current MA-14 through MA-112 PRO range, though some remain available through third-party retailers. The rest of this guide focuses on what Medify actively sells today.
Compact & Budget Tier — MA-14, MA-22, and MA-15
These three models cover bedrooms, home offices, and small apartments, and they're where Medify's lowest per-unit prices sit — though, as covered further down, not necessarily its lowest running costs.
MA-14 is the entry point: a desktop unit rated for roughly 470 square feet per hour of continuous circulation, or about 213 square feet at the more realistic 30-minute mark. Its 3-stage filter (pre-filter, True HEPA H13, activated carbon) delivers a CADR in the neighborhood of 70 CFM. Fan noise runs from a genuinely quiet ~21 dB on low up to 48–55 dB on high, and there's no smart layer at all — just physical speed buttons and a sleep setting. It's a reasonable pick for a small bedroom or a desk, not a shared living space.
MA-22 steps up to a 360° intake tower with a touch panel, a programmable timer, child lock, and a filter-life indicator — controls the MA-14 skips. CADR breaks out to roughly 74 CFM smoke, 82 dust, 75 pollen, and 78 PM2.5, with coverage around 555 square feet per hour. Noise runs 21.3–52.4 dB across its speed range. It sits awkwardly close in specs and price to both the MA-14 below it and the MA-25 above it, which makes it the one model in the lineup that's easy to skip unless the exact size or shape fits your space.
MA-15 takes a different approach: two smaller filters, one on each side of the housing, each running the same pre-filter/H13/carbon stack (a UV-C variant adds a fourth stage). Coverage lands around 585 square feet per hour with a CADR near 78 CFM, and it's notably quiet — 26.1 dB low to 45 dB high — which is why it shows up often as a pair in bedrooms. The MA-15 SMART variant is the same hardware with Wi-Fi and Alexa control layered on, bumping rated coverage to about 660 square feet per hour and giving you the only voice-controlled option in the sub-MA-25 range.
| Model | Coverage (per hour) | CADR (approx.) | Noise range | Smart features |
|---|---|---|---|---|
| MA-14 | ~470 sq ft | ~70 CFM | 21–55 dB | None |
| MA-22 | ~555 sq ft | ~74–82 CFM | 21.3–52.4 dB | None |
| MA-15 | ~585 sq ft | ~78 CFM | 26.1–45 dB | None |
| MA-15 SMART | ~660 sq ft | ~78 CFM | 26.1–45 dB | Wi-Fi, Alexa |

Mid-Range Tier — MA-25 and the MA-35 Wall-Mount
MA-25 is the model I'd point most apartment dwellers toward, especially anyone with a single cat or dog and a living room in the 400–800 square foot range. Its tempered-glass touch panel controls a dual-side filter setup with a combined CADR around 110 CFM smoke, 123 dust, 123 pollen, and 116 PM2.5 — AHAM verified — with coverage up to roughly 825 square feet per hour. Noise sits in the 35–52 dB range across speeds. The one recurring complaint in long-term ownership reports is a fan bearing that can develop a rattle after a couple of years of heavy use; if that happens, Medify's customer service has generally replaced affected units under warranty rather than leaving owners to deal with it.
MA-35 breaks from the tower format entirely — it's designed to mount on a wall, with a floor stand sold separately, which makes it a genuine option for nurseries or high-traffic rooms where floor space and curious hands are both a concern. It covers roughly 640–656 square feet in 30 minutes with a CADR around 290 m³/h, and adds a toggleable ionizer, night mode, and a glass touch panel with child lock. Noise tops out under 66 dB. It's the one model in the current lineup built specifically around out-of-reach placement rather than raw capacity.

Whole-Home Tier — MA-40 and MA-50 V3.0
This is where Medify sees the bulk of its sales, and for good reason — the MA-40 is the brand's best-known model and the one most frequently recommended across owner communities. Rated for about 1,793 square feet per hour (roughly 896 at the more conservative 30-minute mark), it runs a CADR around 406 CFM on the standard H13 build (the H14 UV variant runs slightly lower, around 380 CFM, trading some raw airflow for finer capture and a UV-C stage). It's a genuinely capable living-room or open-plan unit, and I've had one running through two full winters without issue beyond a slightly chilly draft directly in front of it — it moves enough air that you can feel the cooling effect if you're sitting close.
The catch, and it's a real one: an earlier version of the MA-40 included a built-in air-quality sensor and an automatic mode that adjusted fan speed to conditions. Medify removed both in a later revision — without changing the model number or the price. What you get today is fan speed control, a timer, a sleep setting, and a filter-change indicator; the unit no longer reads or reacts to the air around it. If automatic response to smoke or dust spikes matters to you, that's a meaningful downgrade to know about before buying, and it's worth weighing against a sensor-equipped alternative in our best air purifiers for large rooms roundup.
MA-50 V3.0 sits a tier above on raw capacity, using an unusual 4-sided HEPA filter design that pulls air from all four faces of the unit. Coverage runs up to roughly 2,640 square feet per hour, with a CADR around 352 CFM smoke, 379 dust, 397 pollen, and 365 PM2.5 — strong numbers for an open-plan main floor or a great room. Four fan speeds range from a genuinely quiet ~19 CFM sleep setting up to the full 352 CFM, with noise spanning roughly 22–59 dB. Like the MA-40, it ships without an air-quality sensor or auto mode, which feels like a bigger gap at this size and price tier than it does on the smaller models.

Flagship & Commercial Tier — MA-112, MA-112 PRO, and MA-1400 PRO
MA-112 V3.0 is Medify's flagship home unit — a dual-intake tower on wheels with an AHAM-verified CADR approaching 950 CFM (up to roughly 1,009 CFM smoke on the current V3.0 build), and rated coverage as high as 4,455 square feet per hour (some SKUs list up to nearly 6,000 square feet depending on air-change assumptions). Four fan speeds run from a 120.7 CFM sleep mode up to 594 CFM on high, drawing around 95 watts and weighing in at roughly 33.5 pounds. A quirk worth knowing before you buy: the activated carbon layer sits in front of the HEPA media rather than behind it, the reverse of the order used by most competitors — functionally fine, but worth noting if you're used to a different filter stack. Owners running an MA-112 alongside an MA-40 for whole-home coverage have reported years of trouble-free operation, with the main recurring cost complaint being the dual-filter replacement price rather than reliability.
MA-112 PRO is a newer addition, positioned above the standard MA-112, with rated coverage around 2,947 square feet in 30 minutes and the same H13/H14-plus-carbon stack in a console format. It's too recent to have a meaningful track record of owner feedback yet, but it fills the gap between the MA-112 and Medify's commercial equipment.
MA-1400 PRO is squarely a commercial product — a tower rated to clear roughly 1,848 square feet in just 12 minutes, aimed at offices, studios, and larger commercial floors rather than homes. It includes app control alongside its touch interface. Unless you're outfitting a business space, the MA-112 covers essentially every residential use case Medify sells for.

The Real Cost of Ownership — Filters and the Warranty Fine Print
Every Medify model runs the same basic consumable: a combined pre-filter, True HEPA H13/H14, and activated-carbon cartridge that Medify recommends replacing every 2,000–2,500 operating hours — roughly every three to four months if the unit runs continuously. Compare that to Levoit's own guidance for its Core 300 filter, which the company rates for six to eight months under similar use. That gap compounds: over a year, a Medify owner is realistically buying three to four filter sets against roughly two for a comparable Levoit unit, and Medify's filters — particularly the dual-filter set on the MA-112 — sit well above what most competitors charge per replacement. This is the number to run before buying, not the sticker price of the unit itself; our air purifier cost guide walks through the full math by unit type.
There's a second layer to this that most coverage of the brand skips entirely. Medify's "lifetime" warranty is conditional: it requires registering the unit within 30 days of purchase and buying genuine Medify filters on schedule — a third-party or compatible filter voids the warranty outright, according to owner complaints filed with the Better Business Bureau describing exactly that outcome. On July 3, 2024, the FTC's Western Region Director sent Medify's president a formal compliance warning under the Magnuson-Moss Warranty Act, naming Medify as one of five air-purifier sellers flagged over this practice in the same action. That doesn't mean the warranty is worthless, but it does mean the "lifetime" framing comes with a real ongoing cost: you're locked into Medify's own filters, at Medify's own prices, indefinitely, or you forfeit coverage. Factor that into any five-year cost comparison, not just the one-year filter bill.
One thing that is straightforward: every current Medify unit is CARB-certified for ozone emissions, and Medify markets them as tested to zero ozone output. The optional ionizer on select models (MA-35, MA-40, MA-50, MA-112) is off by default and adds negligible particle-removal benefit — leaving it off costs you nothing in performance. For more on what CARB certification does and doesn't guarantee, see our breakdown of air purifier ionizers and ozone safety.
Medify vs. Levoit — The Honest Comparison
Levoit is the brand most shoppers cross-reference against Medify, and the two occupy similar price brackets with very different trade-offs. Levoit's Core and Vital series lean on smart features — Wi-Fi, app control, laser PM2.5 sensors, auto mode — that Medify simply doesn't offer outside the MA-15 SMART. Medify's counter-argument is filtration grade: several of its models use H13 media tested by Intertek, and a couple of its larger units step up to H14, a finer standard than most of Levoit's lineup uses.
Where the comparison tips clearly toward Levoit is running cost and warranty flexibility. Levoit's longer filter-replacement interval and lower per-filter price mean a materially cheaper year-two-through-year-five bill, and Levoit doesn't tie its warranty to exclusive use of house-brand filters the way Medify does. If you want the lowest total cost of ownership and don't mind giving up onboard air-quality feedback, Medify's larger units (MA-40, MA-50, MA-112) still deliver strong raw CADR-per-dollar at the point of purchase — you're trading a lower unit price today for a higher filter bill and a stricter warranty later. Read the full breakdown in our Levoit brand guide if you're deciding between the two, or check Coway if reliability track record matters more to you than either brand's filter economics.
Which Medify Should You Buy?
A single bedroom or home office (under 300 sq ft): MA-14 or MA-15 — the MA-15's two-sided filter and lower noise floor make it the better pick for light sleepers.
An apartment living room, especially with a cat or dog: MA-25. It's the size/CADR balance that shows up most often in long-term owner reports without feeling underpowered.
A nursery or a room where floor space and curious hands are a concern: MA-35, mounted out of reach.
An open-plan living room or a main floor you want covered without buying two units: MA-40 for typical rooms, MA-50 V3.0 if you're pushing past 1,500–2,000 square feet.
Whole-home coverage, or you're running multiple purifiers and want one unit to anchor the largest room: MA-112 V3.0. Budget for its filter cost specifically — it's the single biggest recurring expense in the entire lineup.
A small commercial space or studio: MA-1400 PRO, though at that scale it's worth also checking dedicated commercial options in our industrial and commercial air purifier guide.
Across every tier, size the unit to your actual room using 4–5 air changes per hour rather than Medify's marketing coverage number, which is calculated at a single air change. Our room size guide walks through that math model by model.
Frequently Asked Questions
Q: Is Medify a reputable air purifier brand?
Yes — Medify is a legitimate, established manufacturer with True HEPA H13/H14 filtration tested by Intertek and CARB-certified zero-ozone operation across its current lineup. Its main weak points aren't build quality but two decisions specific to the brand: shorter filter intervals than most competitors, and a warranty tied to buying only genuine Medify filters.
Q: What's the real difference between the MA-40 and MA-50 V3.0?
The MA-50 covers roughly 850 more square feet per hour than the MA-40 and uses a 4-sided filter design instead of a single-face intake, giving it a noticeably higher CADR across smoke, dust, and pollen. Both ship without an onboard air-quality sensor or auto mode.
Q: Why did Medify remove the air-quality sensor from the MA-40?
Medify discontinued the sensor and automatic fan-speed adjustment on a later hardware revision of the MA-40 while keeping the same model name and price point. Current units run on manual fan-speed control only, with no live readout of room air quality.
Q: Do Medify filters really need replacing every three to four months?
That's Medify's own guidance, based on 2,000–2,500 hours of use, and it's shorter than the six-to-eight-month interval Levoit recommends for its comparable Core series filters. Running a Medify unit continuously will genuinely hit that replacement window faster than lower speeds or intermittent use.
Q: Does using a third-party replacement filter void the Medify warranty?
Based on documented customer complaints, yes — Medify's lifetime warranty is conditioned on registering the unit and using genuine Medify filters on schedule. The FTC issued Medify a formal compliance warning over this practice in mid-2024, alongside several other air-purifier brands with similar warranty terms.
Q: Should I turn on the ionizer on my Medify unit?
You don't need to. Medify's ionizers are CARB-certified for zero ozone output and are off by default on the models that include one, and independent testing shows minimal added particle-removal benefit from running it. HEPA and carbon filtration are doing the actual work.
Q: Which Medify model is best for whole-home coverage?
The MA-112 V3.0 is Medify's largest residential unit, rated for coverage up to several thousand square feet depending on target air-change rate. For most homes, pairing an MA-112 in the main living space with a smaller MA-25 or MA-15 in bedrooms covers the space more evenly than one oversized unit alone.
Q: Is the MA-15 SMART worth the upgrade over the standard MA-15?
If Alexa voice control or basic app access matters to you, yes — it's currently the only home model in Medify's lineup with any smart connectivity at all. The filtration hardware underneath is otherwise the same dual-filter H13 setup as the standard MA-15.
Conclusion
Medify has built a genuinely credible lineup around one strength: True HEPA H13/H14 filtration at prices that undercut most brands offering comparable media, from a 470-square-foot desktop unit up to a nearly 5,000-square-foot flagship. What it hasn't built is a smart layer to match — most of the range runs on physical controls with no air-quality feedback, and the MA-40's sensor removal is worth knowing about before you buy expecting one.
The number that should actually drive your decision is filter cost over time, not sticker price. Medify's three-to-four-month replacement interval and warranty terms tied to genuine filters mean the cheaper unit today can cost more than a Levoit or Coway equivalent by year two. If that trade-off still favors Medify for your room and budget, the MA-25 and MA-40 are the two models with the strongest track record among long-term owners, and the MA-112 is the one to reach for if you're covering a whole floor rather than a single room.
Before buying, size your pick against your actual square footage rather than Medify's marketing coverage — check price on Amazon for the MA-40 to see current availability, and compare it directly against the Levoit and Coway equivalents in our other brand guides before you commit to a filter ecosystem you'll be buying into for years.
