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).

Ionic air purifiers attach an electrical charge to the air that passes through the air purifier. This charge, usually a negative charge, then attracts positively charged particles that are floating in the air. This process "weighs down" the particles so that they sink out of the air. Ionic air purifiers are very effective when used in combination with a HEPA air filter. Many times you do not know the nit is working until you change the filter and notice how dirty it is.

Home-Improvement:Interior-Design-and-Decorating] HEPA (High Efficiency Particulate Air) filters are recommended by allergists and medical professionals for the removal of all dust particles in the size range of droplet nuclei from the air. Home-Improvement:Interior-Design-and-Decorating] Many people mistakenly assume that an air conditioning only controls the temperature of a living space. Air conditioning also involves the cleanliness of the air.

Yes. Negative ions and ozone can remove particles of a much smaller size than HEPA filters (which are the most effective filter). They can also cover a larger area much more thoroughly. This is due to the fact that filters rely on the air passing through the unit in order to be purified. Most airborne particulate in a room will not pass through a stationary filter though.

The inlet grill draws in dirty air. In most HEPA air purifiers, a washable pre-filter traps larger particles. By definition, a HEPA filter removes at least 99.97% of all particles as small as 0.3 microns. HEPA air purifiers were originally developed by the Atomic Energy Commission to capture radioactive dust particles. Allergens such as pollen, animal dander, mold spores, and dust get trapped in the filter.

Although other corona-based air purifiers are not rated (because they fail to move enough filtered air to obtain a rating), Kronos™ standalone air purifiers are CADR rated. The Kronos™ standalone product line has a range of CADR ratings to allow the consumer to select the correct size Kronos™ air purifier for the room in which the consumer will be utilizing the product.

Kronos™ products filter and purify the air through the use of a reusable, cleanable collection grid. Kronos™ standalone products have been specifically designed to allow the grid to be cleaned in a standard consumer dishwasher. Kronos™ filters can be replacable in applications where a disposable filter is prefered.

By providing HEPA quality air filtration without the filter, Kronos™ products are less expensive to operate. Why? Kronos™ products use less energy because they do not use a fan to force air through a fabric filter and they eliminate the high cost of replacement filters.

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.

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.

ASHRAE 52.2, "Method of Testing General Ventilation Air-Cleaning Products for Removal Efficiency by Particle Size," is the most common standard used in the air filter industry for determination of air filtration efficiency. Kronos™ products tested at an independent ASHRAE 52.2 certified facility in September 2003 concluded that Kronos™ products provided "better than HEPA results".

The Environmental Protection Agency has determined that almost 90% of the people spend their time indoors. This means that indoor air quality is much more important than outdoor air quality for most people. HEPA (High Efficiency Particulate Air)...

Biozone? Air Purifiers clean the air in 2 ways, inside and outside of the unit. Air inside the purification chamber is exposed to intense germicidal UV (UVGI) light that produces a purifying plasma. This destroys bacteria, fungi, viruses, and other pollutants (including unpleasant odors). This 'ultra-pure' air then carries the purifying plasma and its purifying results to the air and surfaces throughout your home or office.

Virtually all apartments provide air filters for their tenants. Normally, cost is the primary consideration given to air filters for HVAC systems. As a consequence, you are not likely going to get the best air filtration possible. We recommend you contact the Property Manager and explain your desire to obtain a higher-quality filter in your HVAC system.

Negative ion and ozone air purifiers clean the air inside the same way nature does outside, by emitting the world's most powerful and pure air-cleansing agents: negative ions and moderate amounts of ozone.

For optimal performance, we recommend that you change all Blueair air filters every six months. This will guarantee that your Blueair air purifier will continue to work effectively and efficiently to provide you with clean air. Join the Clean Air Club, achoo! ALLERGY's Filter Replacement Program, and you'll receive free reminders when it's time to change your filters.

Yes, you may vacuum the Blueair air filters with a HEPA vacuum cleaner if the filter is dusty; however, it is still recommended that you change your Blueair air filters every six months to receive optimal performance.

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 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.
