Twenty brands were tested and factors such as construction features, availability, reliability, efficiency, and cost were considered.


**NOTE** These reviews are for units that are integrated into a home's air duct system and are typically called whole house units. You can also check out our ratings of portable units.

AIRPURA


★ ★ ★ ★ ★

ALPINEPURE


★ ☆ ☆ ☆ ☆

This brand is from WATERFURNACE INTERNATIONAL. The brand offers nothing very special and is only available from dealers of their geothermal systems.

AMAIRCARE


★ ★ ★ ★ ☆

The AIRWASH WHISPER 350 features high efficiency backward curved fans as well as an optional VOC canister. The brand is reasonably priced, backed by a good guarantee, and is easily purchased by the do-it-yourself customer.

AMERICAN STANDARD

This brand is from DAIKIN GLOBAL and the AMHP-250-UPD is a five stage air cleaner. The unit offers variable speed airflow control and the backing of a truly global brand. They are only available through their HVAC dealer networks for the various brands.

FIVE SEASONS


★ ★ ☆ ☆ ☆

The FSHEPADM400 is made in Canada and offers optional variable speed motors. They offer standard efficiency units but it is unclear as to how you would go about purchasing one of them.

FRIGIDAIRE


★ ☆ ☆ ☆ ☆

The N-HEPA DM400 units feature three step filtration with an optional VOC post filter. They are really very average units as far as technology but they have familiar brand names put on them so the cost is higher than other Nordyne brands.

GENERALAIRE


★ ☆ ☆ ☆ ☆

The AC500 are average units but they do have a two speed motor even though it is controlled by a manual switch. They are typical bypass type units that are available in the USA and Canada but only through a very limited dealer network.

GIBSON


★ ☆ ☆ ☆ ☆

This is one of the value brands from NORTEK GLOBAL HVAC. they are going to cost less than their "flagship" brands. They are identical in all ways except they will have an even more limited distribution network.

GREENTEK


★ ★ ★ ☆ ☆

This brand is made by IMPERIAL AIR TECHNOLOGIES. The units are available in two sizes (200 or 300 cfm) and feature three stages of filtration. They use ECM variable speed motors and are backed by a very good guarantee but you are more likely to purchase one with another brand name on it as they make many of the name brands.

PUREAIR


★ ☆ ☆ ☆ ☆

The 1200HS PLUS features partial bypass units that have their own ECM variable speed motor rated at 1200 CFM.

SKUTTLE


★ ★ ☆ ☆ ☆

The main thing that they have going for them is the engineering of the motors and the design for the airflow. Their unique push/pull design where the very quiet ECM motor is between the filters allows for very quiet operation. The motors have two speeds and are backed by a good warranty but their controls are not really state of the art.

TAPPAN
