The most expensive air filters are not always the best for your air conditioning system. Ask a professional which one will work best for your system.
Are you unsure which type or brand you should use?
Are you using the right size?
Do you know how often to replace them?
There are many types but washable, poly and pleated are the most common.
How often do we need to replace it? This is the most common question we answer.
This depends on a number of things, like how well your house is insulated, if you have pets (how many pets and the kind of pets) and if you have people coming in and out of the house all day. Pleated material can last up to 90 days.
