October, 27th, 2016
When it’s time to change your air filter, do you put much thought into the replacement filter you purchase, or do you just select the cheapest one and forget about it for a few months until you remember to replace it again?
With air filters you definitely get what you pay for, and your home’s indoor air quality is not the place to cut corners. We want you and your family to live happy, healthy lives, so we’re here to help you learn how to choose the right air filter for your home.
What Toxins Are In Your Home’s Air?
So, if an air filter is meant to remove the toxins in your home’s air, and if different filters are designed to remove different levels of small particles called microns, you need to know what types of toxins you’re dealing with so you can choose the best filter for you home. Common household toxins include:
- Items that can catch fire (natural gas, kerosene, oil, wood, etc.)
- Allergens that can cause adverse reactions (pollen, pet hair and dander, etc.)
- Items that can harbor mold and bateria (deteriorating insulation, damp carpet, pressed wood products, etc.)
- Run-of-the-mill household cleaning and maintenance products (bleach, detergents, etc.)
- Outdoor pollutants that have found their way indoors (radon, pesticides, etc.)
So, How Do You Choose The Right Air Filter
- Look for one with a high rating. Each filter is assigned a Minimum Efficiency Reporting Value (MERV). The MERV rating ranks air filters on a scale from 1-20, and you’ll want one with a rating between 8-13. Filters rated lower than 8 won’t remove enough microns from your home’s air, while filters rated above a 13 may be far too strong and can even restrict airflow within your home.
- Find one that’s strong, but not too strong. You’re likely going to want a pleated air filter. Pleated air filters are able to remove about 45% of pollutants and have an average MERV rating of about 10-13.
- Be sure to replace it regularly! 1” filters need to be replaced every 2-3 months while 3”-5” filters can get away with being changed yearly.
