Honeywell Air Purifiers FAQs

Honeywell Frequently Asked Questions

How quiet are Honeywell air purifiers?

All Honeywell air purifiers are fairly quiet. The QuietCare air purifier offers patented sound-reducing technology which provides quiet operation, particularly on the lower fan speeds. With a specially designed fan blade, a rubber isolated motor mount, padded feet, and added insulation, the Honeywell QuietCare air purifier is both quiet and efficient.

How many filters do Honeywell air purifiers use?

Both the Honeywell QuietCare and Enviracaire Air Purifiers (the basic division between the smaller and larger Honeywell models available) use two filters, a true HEPA filter that removes at least 99.97% of common household particles as small as 0.3 microns and a carbon pre-filter that traps large air particles while adsorbing nuisance level smoke and odors.

When do I need to change the filters in my Honeywell air purifier?

Fortunately, Honeywell air purifiers contain a long life HEPA filter which typically lasts you anywhere from 3 years to 5 or more. Just remember vacuum twice a year! The pre-filter will last an average of three months. While the bulk of this filter, the non-woven polyester, will continue to remove large, visible particles well beyond three months, after this time, the impregnated carbon, which is solely responsible for odor and smoke removal, will have adsorbed as much as it can. Simply put, the carbon can't hold any more smoke or odor after the three months or so.

How do I change the filters in the Honeywell air purifiers?

To change the pre-filter for the Honeywell QuietCare air purifier, simply disconnect the unit from the power supply to ensure safety. Next, unscrew the locking mechanism by turning it counter-clockwise. Remove end-cap from unit and remove filter assembly. Undo the velcro fasteners and remove used pre-filter. Install new pre-filter by securing it around the HEPA filter with fasteners provided. The prefilter comes in a large universally sized sheet, so for this model you can either tear it along the perforations or, more cleanly, cut along the perforations to trim it to the right size for you machine. If you are replacing the HEPA filter, you would wrap the prefilter around the stackable replacement HEPA drums (number of filter drums varies based on which model you have). Then, reinstall the entire filter assembly. Replace the end-cap, and insert and tighten locking mechanism by turning it clockwise. Finally, discard the filter and plug the unit back again to continue receiving clean, fresh air.

What is the Intelli-Check Monitoring system?

The Intelli-Check Filter Monitor serves as a convenient guideline for replacement of the pre-filter. Based on the Honeywell air purifier's hours of use and operating speed, the Intelli-Check Monitoring system will alert you when it's time for a new filter. When the indicators light up, it's time to replace the filter.

Can any of the filters in Honeywell air purifiers be cleaned and reused?

The HEPA filter is designed to be vacuumed twice a year and reused for 3-5 years. The Honeywell pre-filter, however, cannot be washed and reused if you expect to have continual odor removal. The carbon in the prefilter is not longer effective with removing smoke and odors after three months, so while the polyester of the filter will continue to trap visible particles, the carbon is effectively spent. Once the Honeywell Intelli-Check Monitoring System displays a dirty pre-filter warning, the Pre-filter should be replaced.

Where should I use my Honeywell air purifier?

Use your Honeywell HEPA air purifier anywhere you need fresh, clean air. You can use it in the bathroom, kitchen, bedroom, basement, or family room.

What type of warranty is offered for Honeywell air purifiers?

The Honeywell QuietCare and Enviracaire air purifiers both come with a five year limited warranty. This limited warranty covers repair or replacement of the unit if found to be defective in material or workmanship, within five years of the date of purchase. Be sure to fill out and return your warranty card within ten days of your Honeywell air purifier purchase to activate your warranty.

What particles do Honeywell air purifiers remove?

The Honeywell Quietcare and Enviracaire air purifiers contain a HEPA (High Efficiency Particulate Air) filter that is guaranteed to remove 99.97% of all particles as small as 0.3 microns from passing air. The HEPA filter and Honeywell carbon pre-filter work together to remove particles like pollen, dust, tobacco smoke, animal dander, germs, bacteria, and mold spores with near 100% efficiency.

Do Honeywell air purifiers produce ozone?

No. There are no Honeywell air purifiers that we offer that produce ozone. Ozone is a powerful lung irritant produced by some air purifiers. But Honeywell air purifiers do not produce or emit any ozone, which will ensure that your air stays fresh and clean.

Who should use Honeywell air purifiers?

Any Honeywell air purifier can be used by allergy and asthma sufferers to guard against unseen airborne allergens. You can also use the Honeywell QuietCare or the Enviracaire air purifier if you want to protect yourself and your family against the unseen airborne pollutants in your home.

How much energy do they use?

In reality, very little. Most use less power than a traditional incandescent light bulb. Remember, the only real moving component or powered part of an air purifier is the fan motor.

Do Honeywell air purifiers have any special features?

All Honeywell air purifiers not only come with a permanent true HEPA filter, but also Intelli-Check Monitoring System, and patented SurroundSeal technology which helps to minimize air leaks and ensure that the air passing through the Honeywell air purifiers passes through all of the filters.
