According to the EPA, the air in your house may be up to 5 times more polluted than the air outside, and we spend approximately 90% of our time indoors! Indoor air pollution is caused by mold, viruses, dust mites, bacteria, pet dander, and the outgassing of chemicals used in the production of furniture, paint, carpet, cleaning supplies, candles, air fresheners...Yep, pretty much everything in your house. This is why an Oreck Air Purifier has been cleaning the air in our house since 2004. We have an Oreck XL like the one pictured above. It works great, it's easy to clean, and the filter parts are easy to find and replace. Ours has three settings: low, high, and silent mode. Silent mode is good during the day and we use the low setting for white noise in our bedroom at night. Especially great for folks with allergies and asthma. Price Oreck Air Purifiers Here
