While there are many reasons to freshen your HVAC air filter regularly
– including lowering your utility bills and lessening the strain
on HVAC equipment – one primary reason is to enjoy cleaner indoor air.
How Do Fresh Filters Clean the Air?
When filters become clogged with dust, dirt and other pollutants, this
debris eventually starts making its way through the filter’s fine
mesh. Regularly freshening up the filter (with a good cleaning or by replacing
it) allows it to continue doing its job. A fresh filter is also less likely
to harbor mold and mildew.
When to Freshen the Air Filter
In general, you should check the filter monthly and change or clean it
when it appears dirty. You shouldn’t wait longer than three months
to change or clean the filter. For many homes, a new filter every three
months is just right. You might need to freshen yours more often if any
of these situations apply:
- You own a cat or dog.
- Someone in your home smokes or has severe allergies.
- Your climate is dusty and you regularly open the windows.
How to Change or Clean the Air Filter
Changing a disposable filter is easy:
- Turn off the heating or cooling system.
- Find the service panel, which may be in a return air vent or inside the
furnace, and remove the cover.
- Remove the old filter and note the size. Stock up on new ones at your local
hardware store or home center.
- Slide a new filter in place. Make sure you insert it the right way based
on the arrows on the filter.
- Replace the panel and you’re all set.
Cleaning a reusable filter is just as easy:
- Turn off the heating or cooling system and find the service panel. Remove
- Vacuum it to remove the largest pieces of dust.
- Hose down the filter to remove smaller particles from the screen. Allow
the filter to dry completely.
- Reinstall it in the housing and replace the panel.
Choosing an Air Filter
Along with changing the filter regularly, you also need to find the right
type of filter for your home. Even the lease efficient filters are designed
to trap large particles without a problem, including:
- Dust mite allergens
- Animal dander
- Some types of mold spores
