How to Buy an Air Purifier

Pet dander, cigarette smoke, ozone, dust and many other allergens lie trapped in homes, and if they are not removed, they will acerbate health problems or even cause them. That's why the decision to buy an air purifier is an important one. Air purifiers are a necessity for people who suffer from allergies and asthma, but everyone can reap the benefits of one of these cleansing devices.

Instructions

• 1

  Determine why you need an air purifier. If you have a dog or cat, pet hair or dander can build up no matter how carefully you clean. Cigarette smoke, excessive use of cleaning or chemical products, and daily dust and ozone also necessitate the use of an air purifier. Different air quality issues require specific features and filter types.

• 2

  Do a spot check of your home. Some areas may need an air purifier more than others. In that case, you need to look at compact, powerful models that can run continuously without problems. If your child has asthma, buy a small air purifier for their bedroom.

• 3

  Compare air purifier features. Some air purifiers are equipped with hepa filters, which block out 99 percent of airborne bacteria and particulates. Air purifiers with hepa filters are an excellent choice for people with allergies or other respiratory problems. Larger models have remote controls and multiple speed settings.

  Research available air purifiers. This is the best way to find an air purifier for your home or office. Check with the local medical supply store to look at purifiers firsthand before ordering anything online.

• 5

  Consider filter maintenance. Except for very small office models, air purifiers contain filters that require replacement every 7 to 35 months. Hepa filters last the longest, but are more expensive. Cleaning the filter regularly with a damp cloth will increase the filter's life span. No matter what air purifier you buy, proper filter maintenance is essential to keep it running smoothly.
