HEPA Air Purifiers
PuroAir 130i HEPA Air Purifier with Filter
A compact HEPA purifier with a carbon layer, Wi-Fi control and a spare filter for bedrooms and living areas. Two different coverage figures appear in the listing.
Floor Area
1600 square feet; up to 2,600 sq ft in one hour claimed
A pair of tower HEPA purifiers for households that want air cleaning in two rooms from one purchase. Filters and the UV-C bulb are parts to replace over time.
A large room purifier bundled with a year of replacement filters, aimed at smoke, odors and pet dander. The spec table describes a different model, so dimensions and weight need confirming.
A large room purifier for homeowners who want auto sensing and no filter changes for years. It suits open plan homes and basements, but runtime noise, size and power use are not listed.
Floor Area
1,650 sq ft in up to 1 hour (AHAM AC-1, 1 ACH, max speed)
A quiet, app connected HEPA purifier with a detailed particle sensor for bedrooms and living rooms. The filter life figure assumes a specific test pattern, so real use may differ.
Floor Area
Up to 1208 sq ft
Filter Type
Sealed HEPA plus activated carbon, separately replaceable
A heavy carbon-filtered air purifier built for tobacco smoke in large rooms. It weighs a lot, and the particle stage is rated by a percentage at one size threshold only.
A tabletop HEPA purifier for a small bedroom or nursery that ships with a spare filter. Coverage is modest and filters need changing a few times a year.
A pet focused air purifier that pulls floating hair into a see through compartment and filters dander and odor. Coverage figures disagree within the listing.
Field Controls TRIO PLUS 5-Stage HEPA Air Purifier
A multi-stage purifier with HEPA, carbon and UV for very large rooms or open areas, certified by AHAM and CARB. The listing gives no filter life or airflow rating, so running upkeep is unknown.
A quiet bedroom size HEPA purifier with automatic fan control and app data. The coverage claims conflict across the listing, so treat it as a single room unit.
A small, quiet HEPA purifier with activated carbon and a color-coded air quality ring. The listing gives two very different room sizes, so treat the coverage as unconfirmed.
A tall purifier and fan that cleans and moves air in living rooms and bedrooms with app control. Its large room figure is at a slow single air change, so smaller rooms get cleaner air faster.
A small, quiet HEPA purifier for a bedroom that needs smoke, pollen and pet dander control. The listing gives no clean air delivery rate, so treat the rated floor area as the sizing guide.
A large HEPA purifier with three cleaning levels and a Turbo Clean setting for big rooms. Dimensions, noise level and filter life are not given, and the coverage figures use different bases.
A compact tower purifier for a large room, with a sensor, Auto mode and an app that tracks filter life. Odor handling comes from a carbon filter, so heavy smoke removal depends on the room size.
A small desktop air purifier for a bedroom or office, rated for a single room. The listing gives two different noise figures and no filter life or airflow rate.
A white HEPA air purifier for large rooms, with auto mode, an air quality display and a quiet sleep mode. The coverage figure is the listing's own, and filter replacement timing is not listed.
