This filter is already making a positive difference in the AC unit perfomance. It has caught seeds, feather and other stuff that was surely getting into the AC before. It has to be an improvement for the internal working of the AC. Happy to add it to the outer ring and watch it work. Get one for your AC.

There's not much to it other than what you see in the photos. It's an attachment with a wiring screen, the same as you'd find on a screen-door in the Midwest.If you're pressed for time and can't make your own, get it, but you'll easily save yourself a lot of $ if you make it yourself.

If you plan to keep and continue to use your portable A/C unit this is a must have item! In about 2 weeks time of use I couldn’t believe how much dust and debris this collected and stopped from being sucked into my unit.Not to mention both the exhaust and intake hoses are blowing and pulling through the screen in the window frame that I thoroughly cleaned before installing the venting.Yes you will have to clean this filter but it’s extremely easy to remove/reinstall and clean using just your kitchen sink sprayer. HIGHLY RECOMMEND THIS!

So this was very namebrand specific and too small but if you have the stuff that you can put around windows and stuff like that, that is kind of tacky but comes right off and can even be reused, people with boats use it people with old houses use it, it has a Play-Doh and silly putty put together quality, it's just perfect, I put that around it and it's sat inside the hose just perfectly. America is about ingenuity. I wouldn't try to use tape that would go wrong on you.

At first I thought it would be difficult to remove, but it is not. I took it off and rinsed it with no problems.It won't catch small particles, but keeps bugs out. I am told that the air going through it never gets inside the house anyway.

Pros: Works well in terms of pre-filtering and keeping bugs out. You may be surprised how much it catches. Easy to install and remove for cleaning. Easy to clean-- just run it under the water tap, and let air dry.Cons: Doesn't fit very tightly, can come lose easily if you're not careful when pulling on hose during movement of the AC unit. Adds more small gaps to the hose setup, due to duplicating those that already exist in the AC hose fitting's design. Is too expensive for what it is.I'm buying a second one for my exhaust hose. I just wish they fit better and were cheaper or had been INCLUDED WITH THE AC UNIT!

This is a MUST HAVE item for your Whynter ARC portable a/c! I was amazed during routine cleaning of the unit's filters to see how many tiny gnats were stuck in there!!! The intake and exhaust hoses are on the INSIDE of the window's screen which these gnats were able to penetrate. The few weeks of humid, rainy weather were responsible for these tiny invaders. I routinely clean all filters on a weekly basis to be sure to have good air flow and help extend the life of the a/c unit. Although it was a bit tricky to remove this pre-filter the first few times, it gets easier each time and well worth the effort. It's durable and simple to clean. Small investment to protect your a/c!

Keeps wasps and other insects out.
