Yes, they are able to trap a high percentage of the airborne allergens and irritants that flow through the filters. However, remember that an air purifier is only one step in getting rid of dust, mold, Volatile Organic Compounds, smoke odor, pet dander, or pollen.
Air purifiers keep your lungs healthy. Consistent exposure to dust, pollen, dander, and other airborne particles can cause long-term breathing and health issues for you and your family. Using an air purifier in your home gives you the confidence that your lungs will be healthy for years to come.
What are air purifiers supposed to filter out — and do they actually do it? Most filters on the market are designed to capture particles like dust and pollen, but don't catch gases like VOCs (volatile organic compounds) or radon. That would require an adsorbent, like activated carbon.
The best air purifiers on the market, specifically designed to remove dust, utilize HEPA (High-Efficiency Particulate Air) filters. Effective HEPA filters can remove up to 99.97% of airborne particles, helping you effectively control and reduce dust inside your home.
Some are much more energy efficient than others. To put this into perspective, a lamp uses approximately 60 watts and a computer uses 365 watts. Using an air purifier probably isn't going to impact your electricity bill tremendously.
