Does Your Air Filter Affect Your Allergies?
One of the most important parts of your furnace is your air filter.
Luckily, it’s also one of the least expensive.
By changing it on a regular basis, you’re helping your furnace run more efficiently. You’re also preventing more pollutants and contaminants from entering the air supply.
It matters which air filter you get. Sure, you can purchase them in bulk from your local big box store for pennies. But that doesn’t mean they do your system any good. Here’s how to determine the best air filter for your home.
You might have noticed the acronym HEPA on some of the air filters you can buy. You’ll also notice that same acronym on home appliances such as vacuum cleaners, air purifiers, and others. HEPA stands for high-efficiency particulate arrestance. HEPA filters are designed to remove certain particles, such as pollen, dust mites, and other allergens, from the air.
The higher the HEPA rating, the more allergens they will remove. This will keep your indoor air cleaner, which means it will also keep your HVAC system operating better for the long term.
Of course, it’s also important to ensure your furnace can handle a more efficient air filter. It’s not wise to get a top of the line air filter without first checking manufacturers guidelines. HEPA filters are thicker and restrict more air flow. If you don’t use the correct HEPA filter, it can restrict air flow too much for your system, causing it to work overtime, impacting the functionality of your system.
You’ll also find air filters are sold by MERV rating too. MERV – minimum efficient reporting system – is a rating system of 1 to 20 that tells you the particle level that will filter from the air. The higher the rating, the finer the particles that are filtered through the air supply. This also means the higher the MERV rating, the more tightly woven the filter will be.
You can work the two together to find an air filter that works perfectly for your system, and provides you with cleaner air in the process. You may find a basic air filter with a MERV rating of 10 or higher works equally as well as one with a higher HEPA rating.
