The Honeywell QuietCare and Enviracaire air purifiers offer energy-saving programmable controls which allow you to preset the unit to shut-off when you are away and turn on at certain times. This feature minimizes energy consumption and saves you money on your utility bills.

Both the Honeywell QuietCare and Enviracaire Air Purifiers use two air filters, a True HEPA filter that removes at least 99.97% of common household particles as small as 0.3 microns and a Pre-filter that traps large air particles.

All Honeywell air purifiers are extremely quiet. The QuietCare air purifier offers patented sound-reducing technology which provides ultra-quiet operation. 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.

Bluair air purifiers have been EnergyStar certified because they are extremely energy efficient. Blueair's phenomenally low power usage means you can run your Blueair air purifier system 24 hours a day, seven days a week without a jump in electricity consumption.

Fortunately, Honeywell air purifiers contain a permanent HEPA filter which never needs replacing. Just vacuum twice a year! The Pre-filter will last an average of three months for both Honeywell Enviracaire and Quietcare air purifiers.

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. Each filter bar will fill up from clean to dirty. Once the bar is completely full, it's time to replace the filter.

The HEPA filter is designed to be vacuumed twice a year and reused. The pre-filter, however, cannot be washed and reused. Once the Honeywell Intelli-Check Monitoring System displays a dirty pre-filter warning, the Pre-filter must be replaced.

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.

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 Pre-filter work together to remove particles like pollen, dust, tobacco smoke, animal dander, germs, bacteria, and mold spores with 100% efficiency.

No, neither the Honeywell Enviracare nor the QuietCare air purifiers 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.

All Honeywell air purifiers not only come with a permanent True HEPA filter, but also include a remote control for easy programming, an 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.

Use your Honeywell QuietCare or Enviracare Air Purifier anywhere you need fresh, clean air. You can use it in the bathroom, kitchen, bedroom, basement, or family room. If you plan to use your Honeywell air purifier on light-colored carpeting, be sure to place a small mat or rug beneath it to prevent possible carpet stains.

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.

Blueair is the system for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air.

Air purifiers remove airborne particulate from the air. Air is drawn through the filter and particles are trapped in the filter system. The filtered air is then re-circulated back through your home.

Air purifiers take out a lot of the pollutants from our air which can irritate allergies and asthma. These pollutants include airborne particulate as small as 0.3 microns and includes pollen, dust, pet dander, mold spores and smoke.

The 200 series Blueair air purifiers use one HEPASilent filter that traps airborne particles like dust, pollen, bacteria, animal dander, and mold spores, while the models above the 200 series use three HEPASilent filters for improved air purification. Optional Smokestop filters (with a layer of activated carbon) remove odors, fumes, and gaseous pollutants. The Blueair AirPod uses one HEPASilent filter that does not contain activated carbon.

Whether you're using the Blueair AirPod or the Blueair 601 air purifier, it's great to use in your office, kitchen, bathroom, bedroom, or family room. No matter where you put your Blueair air purifier, rest assured that you're using efficient and effective air purification technology.

Kronos™ air purifiers provide HEPA quality filtration without a filter. In comparison to standard HEPA filters, Kronos™ air purifiers provide better air filtration - a Kronos™ consumer air purifier will remove 99.97% of 0.1 micron size particulates and 99.995% of 0.3 micron size particles (compared with a standard HEPA filter which only removes 99.97% 0.3 micron size particles).
