The largest of these particles will eventually come to rest and appear as dust. Smaller particles may come to rest, but with even the slightest disturbance will re-suspend into the air. These particles are very small, and come from natural sources such as dust and pollen and from manmade sources such as tobacco smoke or exhaust. The air cleaner is installed on or near the furnace/air handler and removes the particles that travel with the air that circulates through your heating and cooling syste

Allergies (24 hour cycle): When seasonal allergies spike and outside air quality is at its worst, choose this option to run your air cleaner continuously for 24 hours then turn off. Bars are added to the filter life indicator section of the display in increments until it is time to change the filter, at which time all the bars will flash. Your filter will generally last a year, but this depends on a number of factors including your environment, construction details, pets, how often you run your

Particles are measured in microns, which is a unit of measure used for very small things (1 micron = 1/25,400 inch). For reference, the diameter of a human hair is approximately 100 microns. Figure 2 shows the size of various particles that can be found in the air. Your model 4200 or 4400 with genuine Aprilaire SelfSeal™ filters is a highly efficient air cleaner. The removal efficiency defines the percent of particles entering the air cleaner that are trapped (see Table 1). Until now, the air cl

The visible household dust particles, and nearly all pollen and spore particles, therefore, can be caught and permanently held, very easily, if you can get them to the air cleaner. With central high efficiency air cleaners, the blower of your heating/air conditioning system performs the air movement function. Continuous air cleaning will be accomplished when your thermostat is set for continuous air circulation (“Fan On”). If continuous air cleaning is not required, or desired, set your thermost

Should your new indoor air conditioning coil require professional cleaning in the next 10 years while properly using an Aprilaire Air Cleaner, we will pay $100 toward the cost of having the indoor coil cleaned by a licensed contractor. This commitment applies to new HVAC equipment with a new indoor air conditioner coil (less than six months old) installed with an Aprilaire Air Cleaner. The Aprilaire Air Cleaner must be installed by a licensed HVAC contractor. The Aprilaire Air Cleaner must be pr

Normally once the heavy particles “fall out”, they are only reintroduced to the air by vacuuming, or similarly vigorous activity. Where allergy symptoms, which are aggravated by pollens and spores, are a concern, continuous cleaning is strongly encouraged. To recap, when removing household dust is the major benefit you are seeking, you should operate your air cleaner during and following periods when dust is being generated or “stirred up”. For pollens and spores which aggravate an allergy condi
