Questions this video answers

How do I open the cover on my mini-split indoor unit?

Look for notches on either side of the front cover near the top, then simply lift up on the cover to release it. No tools are needed.

How often should I clean my mini-split filters?

About once a month, though it depends on your air quality. Homes with more dust or pets may need more frequent cleaning.

Are mini-split filters reusable, or do I need to replace them?

Airspool mini-splits use reusable, washable filters, so you just rinse them out and let them dry rather than buying replacements, which saves money over time.

What happens if I don't clean my mini-split's filters?

Dirty filters block airflow, which reduces how efficiently the unit cools in summer or warms air in winter, and it can also disrupt the condensate (water) drainage from the unit.

How do I remove and clean the filter on an Airspool unit?

After lifting the front cover open, pull the filters straight out, rinse them with water, give them a shake to remove excess moisture, then slide them back in and snap them behind the notches to close the cover.

Do I need any tools to access the filters on a mini-split?

No tools are required. The cover lifts off by hand using the notches on either side, and the filters simply pull out.

So if you haven't ever removed the cover of the indoor unit on a mini-split, this is how you do it — specifically for the Airspool unit, and probably in general for other mini-splits as well.

You need to do this in order to remove the filter. You should do that probably once a month, depending on your air quality situation. Just rinse out the filter — it's a reusable filter, so that saves money. But you need to do that, or it's going to affect your heat exchange or your cooling exchange, and it may screw up the condensate water flow in the unit, or out of the unit, as well.

So there are notches right here on either side. You just lift this up, and that's it. Then, depending on what brand of unit you have, you'll probably have something like this — this is what you have on the Airspool unit. Just pull these out. You'll see this one's pretty darn clean, but you would, in theory, rinse this out and then give it a little shake to get the water out of there, and then just slide it back in and get it to rehook behind those notches there. And that's it.
