When Your AC Filters Get Dirty So Fast

Close up of an AC Filter

It can be frustrating to find out that your AC filters clog faster than average. If you always find your filters covered with dirt and dust even with a regular replacement, it is important to figure out why this is happening.

Air conditioning service companies in Utah share the possible causes and what you can do to address the problem:

You have furry pets

As pets shed hair and introduce dirt and pet dander, they can increase the amount of dust and contaminants in your abode. This is especially true if you have multiple pets or hairy cats and dogs. Be sure to groom your pet regularly and vacuum daily to minimize dirt, dust, and hair.

Your thermostat fan is set to ON

When you leave the fan to ON setting, it will operate continuously. This means that the air will circulate through the unit and filter non-stop, collecting dirt and dust faster than the normal. You may want to change the setting to AUTO, which means that the fan will only turn on automatically when the AC is cooling your air.

You use a filter with a high MERV rating

With a higher MERV rating, your filters can trap smaller air particles, giving you better protection against dust and contaminants. The only downside is, they can obstruct the airflow and will have to be replaced frequently. You don’t have to choose filters with the highest MERV rating, though. Those with five to eight rating are sufficient for most homes. An AC technician can help learn more about your options.

If you find your filters clogged up after a few weeks, you may want to consider an air purification system. This will remove a number of particles before they can get to the filter. This system is particularly beneficial if you have multiple pets or if you or a family member has a respiratory condition.
