Medify MA-40 Air Purifier with H13 HEPA, White vs Membrane Solutions MSA3 Air Purifier

These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.

Medify MA-40 Air Purifier with H13 HEPA, White

Rooms around 375 sq ft where a timer and child lock matter

Medify's MA-40 uses a one-piece pre-filter, HEPA and carbon cartridge with three speeds, sleep mode, a timer, child lock and a switchable ionizer. Medify's documents disagree on CADR, wattage, filter life and clearance, and the listing attaches the MA-40UV manual. Register within 30 days for the lifetime warranty.

Published specifications

  • Medify page: AHAM Verifide 373 sq ft; V3.0 manual says 377
  • Medify page: smoke CADR 239 CFM (406 m³/h)
  • V3.0 manual: filter every 2,500 h; Medify page: 3,000 h
  • V3.0 manual: 20 in behind the inlet; MA-40UV manual: 10 in
  • Medify: 22 H x 9.9 W x 10.9 D in
  • V3.0 manual: lifetime warranty, register within 30 days

Strengths

  • Verified room size and CADR by pollutant published by Medify
  • Child lock, timer and switchable ionizer
  • Limited lifetime warranty when registered promptly

Caveats

  • Listing attaches the MA-40UV manual, not the MA-40

Membrane Solutions MSA3 Air Purifier

Buyers happy to commit to the maker's own filters for a mid-size room

The Membrane Solutions MSA3 uses one composite pre-filter, HEPA and carbon cartridge with a filter-recognition sensor that refuses non-brand filters. The maker lists a 112 CFM CADR, but its room-size figures conflict. The filter reminder comes at 1,700 hours, and registration within 30 days adds a second warranty year.

  • Handbook: 7.7 x 13.1 x 21.5 in, 13.7 lb, 44 W
  • Handbook: 1-year warranty plus 1 year if registered in 30 days
