Our top pick is the Midea Cube 50: a certified 49.67 pints a day at ENERGY STAR's 2.01 L/kWh, with a large bucket and a compact, extendable body. Here are six picks by job.
Our top pick is the Vornado EVDC500: evaporative, so no white dust, with a 2-gallon capacity and a frugal DC motor. Here are six picks by room size and type.
Pollen, dust mite debris and dander are mostly large particles, which MERV 12 and 13 filters catch at 90% or more. Our top allergy pick is the Filtrete MPR 1500 (MERV 12).
EPA suggests MERV 13 or the highest your system can handle. Our top pick is the Filtrete MPR 1900, a MERV 13 1-inch filter; here are five more for different systems and budgets.
One purifier that follows you, living room by day and bedroom by night, can beat two that sit still. These certified HEPA purifiers are light enough to carry and strong enough to matter.
A continuous radon monitor shows your short- and long-term averages without lab fees. These are the best we found, and how to use one alongside the EPA's test-then-confirm advice.
A smart purifier earns its Wi-Fi chip with a good sensor and an auto mode you can trust. These certified picks do; we also say which sensor each uses and what it misses.
No single portable cleans a whole house. You either spread certified purifiers through the rooms you use, upgrade the furnace filter, or both. Here is how the options compare.
A media cabinet holds a 4 or 5-inch filter that reaches MERV 13 with less airflow resistance than a 1-inch filter. Our top pick for adding one is the Honeywell F100 cabinet.
The 211i Max replaced the Blue Pure 211+, and it is one of the strongest purifiers AHAM lists at this price: 435 cfm of smoke CADR, very low power draw, and a choice of four filters.
The 411i Max is Blueair's small-room purifier: about the airflow of a Levoit Core 300, a quieter low setting, a particle sensor and app, and power draw lower than most lamps on its lowest speed.
Blueair's Classic 605 was a big steel box for large rooms. It is gone from AHAM's directory and from Amazon as a new unit. Here is what owners and shoppers should do instead.
CADR is the one standardized number for how fast an air purifier cleans a room. Here is how it is measured, how to use it, why smoke CADR is the one to compare, and its blind spots.
Cool mist is the default for most homes and the clear choice around children. Warm mist avoids white dust and feels cozier, but it can burn and it uses more power.
The 200M is the version of Coway's Mighty that drops the ionizer. Same filters, same cheap yearly filter set, three manual speeds, and a sensor-driven Auto Mode.
The Airmega 400 is Coway's large-room machine: two filter sets drawing air from both sides, a smart mode that reads particles and light, and a five-year warranty. It is also expensive.
The Mighty has been the reference mid-size purifier for a decade. It is still cheap to run, but it is no longer in AHAM's directory, it carries an ionizer, and Coway has a successor.
Filter sizes are nominal: a 16x25x1 is about half an inch smaller each way and under an inch thick. Measure the slot, not the old label, and order custom only when no standard size fits snugly.
