What's behind our dehumidifier Ratings? and provide valuable feedback to other members and our testers. A dehumidifier can take that sticky feeling out of a damp basement or crawl space. Humidity levels above 50 percent can breed dust mites, mildew, and mold, which may worsen allergies and asthma. Our latest tests show that the best dehumidifiers aren't necessarily the highest priced.Dehumidifiers use a fan to pull air over two sets of refrigerant-filled coils, which pull moisture from the air and drip it into a tank. All the models we evaluated in our test chamber performed at least adequately overall. But some came much closer than others to the humidity levels we set on the humidistat. And some used less energy or ran more quietly. We've also found that some models handle simulated power outages better than others. Heating, Cooling & Air Quality> During the cold seasons, the dry air from the weather can cause your skin to be dry, cracking and uncomfortable. The humidifiers from hhgregg can help to prevent that by adding moisture into the air.

There are two main types: Warm mist humidifier – Using a heating element, warm steam is released into the room after water is boiled inside the machine. The boiling process may kill more germs and some users prefer breathing in the warmer air.Shower Head Mist Spray Cool mist humidifier – Water vapor is sprayed into the air at room temperature. Black And White Damask Duvet Cover TwinEvaporative cool mist uses a fan to pull air through a filter. Toilet Seats For RvAn ultrasonic humidifier uses an ultrasonic frequency and a vibrating metal plate to break down the water into drops that are then pushed into the air. A cool mist humidifier is generally cheaper and is often recommended by doctors for infants and children. Finding the right humidifier is essential to help you through those allergy and cold seasons by keeping your home moisturized.

Air purifier buying guide Before you buy an air purifier, try some simple, common-sense steps to reduce indoor air pollution. Begin by vacuuming often, banning smoking indoors, minimizing use of candles and wood fires, and using exhaust fans in kitchen, bath, and laundry areas. Test your home for radon gas, which can cause lung cancer (test kits cost about $15). Don't store chemicals, solvents, glues, or pesticides in your house. Minimize the risk of deadly carbon monoxide gas by properly maintaining and venting heating equipment, wood stoves, fireplaces, chimneys, and vents--and by installing carbon-monoxide alarms on all levels of your home.

And don't idle your car, run fuel-burning power equipment, or light a barbecue grill in your garage, basement, or in confined spaces near your home.The better air purifiers do especially well at filtering pollutant particles such as dust, tobacco smoke, and pollen. Volatile organic compounds (VOCs) and other types of gaseous pollutants, however, are another matter. Some portable models with carbon pre-filters are claimed to filter VOCs, known respiratory irritants that arise from adhesives, paints, and cleaning products. But the Environmental Protection Agency warns that such filters are specific to certain gaseous pollutants, not for others, and that no air purifiers are expected to remove all gaseous pollutants found in the typical home. Carbon filters also must be replaced often, typically every 3-6 months, or they stop working--and can even, when full, release trapped pollutants back into the air. The safer course: Heed strict product-label warnings such as "use only in well-ventilated spaces."

Air-purifier models with an electrostatic precipitator remove pollutant particles by charging them as they pass through and collecting them on an oppositely charged metal plate or filter. In the process, they produce some ozone as a byproduct. You'll also find dedicated ozone generators, which produce relatively large amounts of this gas by design. While ozone in the upper atmosphere protects us from the sun's ultraviolet rays, ground-level ozone is an irritant that can worsen asthma and compromise your ability to fight respiratory infections. We believe that air purifiers that emit even small amounts of ozone are a poor choice if someone in your household has pulmonary problems or allergy symptoms. We also suggest that you avoid dedicated ozone generators entirely, given their high ozone emissions.The very best portable models we tested were effective at cleaning the air of dust, smoke, and pollen at their highest or lowest speed. For whole-house purifiers, our recommended models did best at filtering dust and pollen without impeding the airflow of forced-air heating and cooling systems.

The worst models weren't terribly effective at any speed.Keep your home comfortable with air quality appliances Whether you're welcoming a new baby into your home or trying to fight off the pollen and spores of allergy season, air quality appliances can help you improve the air circulation in your home. Close the windows and turn on the air conditioner as your air quality appliances keep clean air moving through your rooms. At Sears, you'll find the humidifiers, dehumidifiers and air purifiers that you need to keep your house or apartment at a comfortable humidity level with filtered, fresh air. When you have allergies, you want to find ways to improve your environment to avoid irritants. Air purifiers will pull many allergens from the air, filtering them through the system so you can breathe fresh, clean air in your home every day. When you use indoor heating appliances, the air in your home can become especially dry. On the flip side, outdoor humidity in the summer can seep into your home, creating a muggy space.
