You’ve probably heard that you need to change your air filters regularly–at least every three months, and more frequently if you have pets or allergies. But with so many different kinds of air filtering devices, how do you know which is best for you and your home? There are three common types of air filters that can be used in home hvac systems: fiberglass filters, polyester pleated filters, and HEPA filters. You may also see washable fabric filters, but these are much less common.
All filters are rated by their Minimum Efficiency Reporting Value (MERV), which tells you a lot about a particular type of filter. The scale goes from 1-16, with higher numbers being more efficient. Consult your air conditioning services contractor to know which air filter to use in your home.
Fiberglass filters are very common, in part because they’re so inexpensive and light. They can be thrown away and are often sold in multipacks, which makes it easier to keep extras on hand. They are usually rated from 1-4 MERV.
Pleated paper or polyester filters are also disposable, and are usually rated 5-8 MERV. They are quite a bit more expensive than fiberglass filters, but also more efficient. Disposable filters are more hygienic than washable ones, as they remove all the dust from your home.
HEPA filters, otherwise known as high-efficiency particulate arrestance filters, are the top of the line HVAC filter. They are great for people with allergies! On the other hand, they restrict airflow quite a bit, cost more, and can only be used with HVAC units that are compatible (otherwise you risk damaging your unit). Visit https://cmheating.com/mountlake-terrace-new-location/ or other experts and ask them about the right filter for your unit.
