Medify Air MA-25: problems, parts and running costs

Checked: 2026-10-19

Summary

The MA-25’s real issues are an ownership bill and a spec sheet that does not hold together: the H13 filter costs $39.99 every 3–4 months, about $120–160 a year, and the manufacturer’s own noise and coverage numbers contradict each other. No independent test outlet has verified this exact model, so treat every spec as a manufacturer claim. It is a fair buy at the $148.99 Medify listed on its own site if you accept unverified performance and budget for the filters.

Common problems and fixes

The noise spec contradicts itself — the manufacturer lists speed 3 at 49.3 dB while the same spec sheet lists “maximum” as 44.6 dBA, and the two cannot both be the maximum. Workaround: treat 49.3 dB at speed 3 as the realistic loud end and listen at that speed before the return window closes. [1]
No independent test covers this exact model — Wirecutter’s 2026 air purifier guide recommends Coway and Blueair and does not mention Medify, Tom’s Guide’s 2026 roundup also leaves Medify out, and Medify’s lab-reports page lists results for the MA-40, MA-50 and MA-112 but no MA-25 report. Treat the CADR, noise and coverage numbers as manufacturer claims. [2][3][4]
The lifetime warranty is conditional — it applies only if the unit is operated per the manual, so follow the manual and keep proof of purchase if you may ever claim it. [1]
The filter is the cost sellers underplay — replacement is $39.99 every 3–4 months (2,500 hours), or $35.99 on a subscription, roughly $120–160 a year. Budget it before buying. [1]

Parts and consumables

H13 True HEPA filter (three layers: pre-filter, H13 HEPA, active carbon composite) — $39.99 one-time or $35.99 on subscription, Medify direct, captured 2024-12-27; Medify recommends replacement every 3–4 months or 2,500 hours. [1]
No other replaceable parts or consumables reported — no spares catalogue, fan, remote or accessory was found for the MA-25. [1]

Yearly running cost

Filters dominate. At $39.99 per change every 3–4 months the source works out to roughly $120–160 a year; the $35.99 subscription trims that slightly. Energy is modest: 28 W running constantly is 160 kWh a year, about $32–40 a year depending on electricity rates. There are no pods, sensors or other consumables.

When it is a good buy

Medify listed the MA-25 at $148.99 on its own site, captured 2024-12-27, with a 30-day home trial and free shipping and returns. At that price it sits mid-range for a CADR-rated purifier of this size; the lifetime warranty and H13 filtration are positives, the unverified performance and the filter cost are negatives. The research found no confirmed third-party pricing below the manufacturer’s own, so no lower street threshold can be named.
