Do Ductless AC Systems Units Have Air Filters?

Written on: August 26, 2024

Checking filters improves the efficiency and resiliency of ductless mini-splits.

When we talk to our western Connecticut customers who have installed ductless mini-split systems in their homes, we always hear rave reviews. Many of these homeowners had depended on loud, inefficient window air conditioners before because their homes lacked the ductwork necessary to accommodate a central air conditioning system.

Ductless A/C, on the other hand, offers effective, long-term cooling that can stand up to the hottest weather conditions that Mother Nature can throw our way! And they do this using compact equipment connected by thin piping. One question we sometimes hear from customers is whether these systems have air filters like central A/C does.

Ductless A/C equipment does have air filters, and in this article, we’ll talk to you about how to locate and maintain them.

Where are your ductless A/C air filters?

Generally speaking, the air filters in your ductless mini-splits are reusable, so you would likely clean them rather than replace them. You will typically find these filters in each of your system’s indoor air handlers.

How do you check and clean ductless A/C filters?

The process for checking and cleaning your ductless A/C filters will vary slightly depending on the manufacturer and model you have. You should consult your manual for specific instructions. However, here is a general guide for checking your air filters:

1. Turn off the indoor air handling unit.
2. Carefully open the front panel. The panel is located near the blower.
3. Slide the filter (or filters) out of the unit.
4. Clean the filter with a gentle spray of water. Alternatively, you can sometimes use a vacuum to remove dirt, dust, and debris, but be sure not to use a vacuum setting that is too high. This could damage the filter.
5. Allow the filter to dry, and then return it to the unit. Turn the unit back on.

As a general rule, it’s best to check your filters once every month during the peak heating and cooling seasons.

Why should you check your air filters regularly?

Keeping up with your HVAC system’s air filters — whether you have a traditional central A/C or ductless mini-splits — is integral to maintaining its efficiency and longevity. Clean, unobstructed air filters allow better airflow into your rooms, which means your system doesn’t have to work quite as hard to keep you comfortable.
These filters are also your first line of defense against airborne pollutants like debris, mold, pollen and bacteria, which can aggravate allergies and asthma, dry out your skin and eyes and increase dust accumulation.

Staying on top of your filter also slows down the wear and tear on your equipment. That means fewer breakdowns and a longer life expectancy.
