Yes, it is ozone free and electrostatic free. It also purifies the air of dust mites.The Holmes air purifier is one of an assortment of products designed to change the air you breathe in your home. The Holmes air purifier is joined by humidifiers, heaters and fans as well as replacement filters for those products. In our efforts to cut back on energy usage, we've added insulation to home and office buildings. Manufacturers create windows that fit tightly and insulate the wall opening to keep any outdoor from coming into the room. Even light switches are now routinely filled with expanding foam insulation from a pressurized can that stops any drafts from coming through.

Our devotion to energy savings is admirable but we have create air quality problems in our homes that did not exist even one generation ago. Air in our homes is not exchanged with outside air frequently. In fact, the only time outdoor air enters a room is when a door or window is opened. We do save on energy by building tight homes and by remodeling to add insulation and remove drafts. However, the air in our rooms can fill with allergens, dust particles and gasses produced by other household equipment. Germs, mold and mildew join fungi and viruses in the air inside our homes. The result for many of us is that the air in our house is more polluted than air in the manufacturing section of a large city. In the past 20 years air purification systems have gained prominence as a way to clean up air in our homes. The Homes air purifier (also referred to as an air cleaner) removes impurities and contaminants from the air we breathe. The benefit for allergy sufferers is clear.

If you have hay fever, breathing pollen and dust leads to frequent and uncomfortable allergic reactions. Mold, pet dander and tobacco smoke frequently contaminant indoor air which can lead to health problems for young children and senior citizens alike. A Holmes air purifier is very effective at removing allergens, pollutants and odors from indoor air. This is accomplished by the use of a fan and filtering system that draws air across and through the filter where airborne particles are captured. The newly cleaned air is returned to the room while the quiet Homes air purifier continues to pull room air through its filter and keeps the indoor air fresh and healthy. As air is drawn through the filters by fans it is cleaned by a high-efficiency HEPA-Type or HEPA filter. On some units the air first passes through a pre-filter which traps large particles of dust, pollen and pet hair and then it moves through the HEPA filter. HEPA-Type filters can remove particles as small as 2 microns wile True HEPA filters remove up to 99.97% of the contaminating particle in the air and can trap particles as small as 0.3 microns.

After air has been drawn into the air cleaner and filtered, a powerful fan returns the cleaned air back into the room. In some cases, ionizers are also included. Ionizers release ions with a negative charge. The result is ions which attract small particles to the negative charge. The resulting group of air pollutant is then more easily caught in the filter as the air passes through. Ionizing air purifiers have been well received by the public. This may be due to the fresh feel of the negatively charged air. If you are outdoors just after a thunderstorm you notice a freshness and crispness to the air you breathe. You may think it's due to rain that washed pollutants from the air and this is part of the process. However, it's the lightning during the storm that releases negative ions and makes the air smell fresh when you breathe it in. Ionizers work in much the same way. Recent question about the safety of some ionizing air purifiers may lead to stricter production standards.

The danger is not the negative ions but the ozone which is produced as a by-product. Outdoors, lightning produces ozone but the gas quickly dissipates over a large area. Indoors, the ozone may be a problem but until testing is complete air cleaners using ionizers continue to be sold. The Holmes air purifier you choose will require a decisions base on your specific needs. The type of filtration system you need is based on the problems you want to eliminate in your home. If allergies are a problem for family members you need a Holmes air purifier that removes pollen, more spores, dust, pet dander and smoke. Your goal is to have the cleanest possible air in your home and to accomplish that you need a unit with a True HEPA filter. This will improve the home air environment for those with allergies or asthma as the True HEPA filtration system removes up to 99.97% of even the smallest particles. Stale indoor air can be caused by smoke, pets, dust, mold or mildew or seasonal pollen.

If allergies are not a significant problem, a HEPA-Type filter removes up to 99% of particles and dust that is over 2 microns in size. Though the tiniest bits of dust and dander are not captured by a HEPA-Type filter, this unit offers ease of use with a permanent filter and yields cleaner, fresher air. Odors in the home are another concern. We love our pets but we don't love the doggy odors or the smell of a litterbox. We live in our homes and we create odors through our daily activities. Cooking odors, smoke, garbage, nurseries and bathrooms are prime causes for homes that don't smell fresh. Supermarketers devote entire aisles to product meant to scent the air indoors and to mask bad smells. An activated charcoal filter enhanced with Arm & Hammer baking soda provides a Holmes air purifier that will totally remove common household odors. The Holmes air purifier is one of several Homes products that are designed to provide solutions to indoor air quality problems we encounter.
