HEPA catches particles. Carbon is what removes the smell.

You already bought one box for this problem. It handled the dust and never touched the smell that made you buy it. That is not a fault in the machine, it is physics. A smell is a gas, and only a deep bed of activated carbon holds on to a gas.

How to choose on this shelf

  • Room first. Airpura and AllerAir publish a square footage for most models. Austin Air publishes none and says why in its own FAQ.
  • Carbon weight second. Austin Air carries up to 15 lb. Airpura runs 8 lb to 26 lb in a sealed canister. AllerAir runs 14 lb to 40 lb. Weight decides how long a smell stays gone.
  • Your problem word third. Smoke, formaldehyde, musty, litter box, fresh paint. Austin Air HealthMate Plus carries the smoke and VOC blend, Airpura F600 is built around formaldehyde, AllerAir AirMedic Pro 5 carries a Vocarb blend.

Not for: steel boxes with a switch and a fan. No app, no sensor, no auto mode, loud on the top speed. If dust and pet hair are the only complaint, a cheaper particle unit clears more air per dollar.

How to choose in four steps

  • 1. Room size

    Measure the room, then match the sq ft

    Length times width. Match that to the sq ft in the product name. Go one size up for open plan rooms or high ceilings.

    Under 400 sq ft: bedroom or office. 400 to 999: living room. 1000 plus: a whole floor.

  • 2. The concern

    Match the filter to the problem

    Allergies, dust and pet dander call for HEPA. Smoke, cooking and chemical smells call for a real bed of activated carbon. For mold and mildew, look at the HEPA air scrubbers, some add UV on top.

    Use the What it is for filter to narrow the list.

  • 3. Noise

    Bedrooms want under 25 dB on low

    The lowest speed is the one that runs all night. The quietest unit here starts at 16.5 dB on its lowest speed. Air scrubbers built for job sites run over 60 dB on high and belong in a basement or garage.

    The Noise filter uses the lowest speed figure the maker publishes, or its only published figure where that is all it gives.

  • 4. Running cost

    Check the filter price and how often it changes

    A cheaper unit with a filter every 6 months can cost more over 3 years than a pricier one changed once a year.

    Where the maker publishes them, the product page shows the filter price and change interval.
