The product is expensive for a plastic air filter device but it’s great to have to keep out and sex and other air quality problems especially if you’re using it in the nursery

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.

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.

Apparently-durable metal screen, fairly loose-fitting, and trapped a lot of dirt for me.Even though my portable aircon intake hose is "pre-filtered" by my sliding door screen, this add-on filter provides additional filtration. I'm a little lazy, so I just vacuum-brush off the add-on's screen---and it sure has gotten dirty even with one-week cleaning intervals. I wouldn't say that the area outside my subject sliding door is particularly dirty, but I'm sure that consumers' such areas will vary in their dustiness. I can imagine how much more quickly the aircon's critical internal passageways would dirty-up, doubtlessly hurting the unit's efficiency/effectiveness---without the add-on filter! If the screen eventually won't clean up with vacuum-brushing, I will use Dawn liquid and a soft toothbrush, then rinse.My add-on filter seemed to fit onto the hose and onto the pass-through-to-the-outdoors adaptor, but I exercise care in attaching and detaching. I also support the hoses with a chair underneath to keep the hoses/filter from unwanted detaching or cracking---due to my full-hose extension to point the unit where I want the cool airflow to go.I guess you could make your own such filter, but this is pretty much plug and play and clean and re-plug, Kind of expensive vs what it probably cost to make, but for me it's worth it to increase the aircon unit lifespan and to somewhat slow down its clogging-caused, probable eventual decline in efficiency/effectiveness.

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!

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.
