Generally, foam filters are the only ones that can be washed-
-but it depends on the foam.
Fiber filters can be synthetic or paper--only washable if you feel reckless.

I have washed the ResMed Standard filter just to see what happened.
It survived just fine. So it can be done in a pinch.

Not to beat a dead horse, but is the AirSense filter washable? ResMed does not mention to wash the filter in its manual so I don’t know. I’m coming from a Resprionics machine, where it had a washable filter.
In a pinch, they weren't designed to be washable, but I've done so. they're cheap on amazon/ebay.

Also, does anyone know if ResMed offers a second filter?
Yes, they make a hypoallergenic filter.

Resprionics ...a Hepa filter.
NO they do NOT have a HEPA filter, they have a 'ultra-fine' filter, it is NOT, by any means, a HEPA filter.
This is a HEPA filter:
It's about 5 inches long.

I wouldn’t be opposed to adding a hepa filter to my ResMed machine cuz I have allergies
Then get a hypoallergenic filter for it.

I change mine every 2 weeks. I have asthma, am allergic to dust and feel the need to keep things scrupulously clean.

Asthma: solution
Allergies: likely to help

This shows a fundamental lack of understanding about how filters work.
The more dust you have on your filter, the less dust (and air) that makes it's way through the fibers in the filter.
You change the filter not to improve
filtration, but to improve *airflow*.

Yes, but it's not a good idea. Many filters washing changes the characteristics of the filter, ( air flow and size of particles removed). Gently blowing it out, with compressed air will help, but better is not being cheap and following the instructions. Jim

No, I did not. I also guess if the pinch was too hard, you could just remove the filter for a couple of nights without causing any damage, unless a sand storm was forecast. Just passing on info from a class I had to take from Caterpillar Corp, on servicing our new $13,000,000 fleet of earthmovers.
Most big equipment makers install gauges to show when filter restriction show filters need changed out. We were taught Never clean the air filters, not even with air, even open them up without new filter sets.
A few tablespoons of dust can gut a V-12 Diesel, our bosses had us blowing them out, in the field with-in ten days. So much for protecting your investment. The bosses cost them more money than they saved. Jim
Pay me, now or pay us later, even more. Rebuilt engines only cost $ 80,000 $$$, each machine had two, plus downtime and labor.

When is the last time you even saw or used a ResMed Standard filter?
They are NOT the same as Respironics filters (either the foam resuable or disposable).
You are going way out on limbs that simply don't need to be traversed.

We have used canned air to flush out the window AC filter.
Probably gentler than a compressor.

Canned air should be ok, also most air compressors have a pressure regulator to control the pressure. My old Tank XPAPs, use washable foam and the white inner filter, I keep a supply of both. All 3 are over 16 years old, and work as well as they did when new. Jim

Do all air compressors have an oil removal device?
I would hate to blow a gob of oil into a filter.
Besides the can is quiet and very portable.

Some compressors are oil less, but most good ones have pressure regulators on them. They also have a safety valve to protect the tank from over pressure. If you want there are moisture-filters that can be added inline to clean the air. They even have oil adders to lube your air tools. A good air compressor doesn't put oil into the pumped air. Jim
