Changing the air filter in your home is an important part of keeping your HVAC system running smoothly. To ensure maximum safety, you must turn off the boiler and set the thermostat to the off position before changing the filter. Take note of the dimensions printed on the existing filter's frame, and make sure the new filter matches this size. It should fit snugly, but not so tight that you can't easily slide it in and out.
A clean filter is essential to prevent dust from entering the HVAC system and reducing its efficiency. A disposable pleated paper filter is a step up from a basic filter, as it can capture even the smallest particles of dust, dirt, and pollen. Check the Minimum Efficiency Report Value (MERV) to see how well the filter can capture particles of different sizes. It's a good idea to check your air filter once a month to see if it needs to be changed before three months.
Your oven's owner's manual will specify the best MERV rating for your oven, and in general, filters with a MERV rating of 6 to 9 should be changed every 90 days, while those with a MERV rating of 10 through 12 should be changed every 60 days. Clogged filters not only affect air quality in a house but also force the oven to work harder to draw air into the system, which can shorten its life. The filter will be easier to change when it is turned off because the air pressure of the blower is usually significant. Replacing your furnace filter regularly can help keep your heating system running efficiently between regular HVAC unit settings.
A new filter can give you your first breath of clean, fresh air, even before spring hits your doorstep this year.
