When air inside your home is heated, it's relative

 humidity plummets, stripping moisture not only

from the air, but from your skin and body, your

wood furniture, fixtures and floors. The Aprilaire

whole house humidifier is perhaps the most efficient

way to add moisture to your home's air.

Introduced in 1973, the Aprilaire High-Efficiency Air Cleaner

has been a silent, low maintenance, inexpensive air filtration

system. It utilizes a simple, remarkably effective HEPA-type

filtering media that actually improves it's particulate-capturing

capability the longer it is used. For particles larger than 5 microns,

efficiency reaches 99%. Even the smallest particles, as small as 

one micron, can be filtered out at 95% effectiveness. The high

density filter unit is attached to your existing heating or

cooling system, where it seizes pollutants from conditioned

air before it is distributed to the rooms of your home.

The Aprilaire Fresh Air Exchanger is a way to

effectively exchange fresh outside air for stale

inside air. The exclusive energy max transfer

core uses the heat of indoor air to warm up the

cold fresh air, recovering about 77% of the energy.

In summer, warm fresh air passes near outgoing

conditioned air, cooling it down. The beauty of

the energy max transfer core is it's use of

enthalpic technology. This technology enables

the transfer of moisture as well as heat. The 

popularity of the enthalpic-type air exchanger

has increased all over the country because of it's

superior ability to control humidity levels in both

winter and summer.
