If you have a portable air conditioner, you know the struggle of that big exhaust hose. It vents air outside, but it also creates a perfect front door for spiders, flies, and other bugs to crawl right into your room. I spent all last summer slapping at mosquitoes that snuck in through my window vent, so I finally grabbed these mesh screens to see if they actually worked.
This 2pcs Round Insect Cover Dustproof Anti-Insect Screen For 130/150mm Air Conditioner Exhaust Duct White Air Conditioner Accessorie review explains whether these cheap plastic guards are worth the effort. They are a simple, budget-friendly fix for a very annoying problem.
What are these insect covers?
These are basic plastic mesh caps designed to snap or fit over the end of your exhaust duct. Most portable air conditioners use a 130mm or 150mm hose, and these covers are sized to fit both. The main appeal here is that they provide a physical barrier so bugs cannot enter your home through the exhaust pipe.
When I bought them, I was mainly looking for something that offered free shipping because I did not want to pay more for shipping than the item itself cost. They arrived in a thin plastic bag after a few weeks. The material is pretty standard lightweight plastic, which is exactly what you should expect for the price.
Why you might want these
The biggest benefit is peace of mind. Without a screen, your exhaust hose is just a wide-open tunnel for moths and beetles to fly into your bedroom at night. Installing these covers blocks that path without stopping the airflow you need to keep your room cool.
They are also incredibly easy to set up. You just slide the mesh over the end of the hose, and it stays put. Since it comes in a pack of two, you have a spare if one gets damaged or if you happen to have two portable units in your house.
Honest pros and cons
- Pros:
- Very cheap and often sold with free shipping.
- Prevents bugs and large dust particles from entering.
- Fits both common hose sizes (130mm and 150mm).
- Extremely light and simple to install.
- Cons:
- Shipping from overseas takes a long time, often several weeks.
- The plastic feels thin and could crack if you handle it roughly.
- You might need a bit of tape to ensure a snug fit if your hose is slightly loose.
- There is no local warranty if the plastic arrives broken.
Who should buy these screens?
If you live in an area with a lot of insects, these are a no-brainer. They are perfect for people who use portable AC units in ground-floor rooms or near gardens where bugs are active. If you are on a tight budget and just want a quick fix for a pest problem, these will do the job.
Skip these if you are looking for a heavy-duty, permanent solution that will last for a decade. If you are impatient and need something tomorrow, the long wait time for shipping will definitely frustrate you. You should also skip these if your exhaust hose is a weird size that does not fall into the 130mm or 150mm range.
What other buyers say
Most people who buy these are happy because they solve a very specific, annoying problem for just a couple of dollars. One buyer mentioned that they had to use a bit of duct tape to keep the screen from popping off during a windy day. Another user noted that while the plastic feels basic, it does exactly what it says on the box.
Most reviews agree that you should not expect high-end manufacturing. You are paying for a simple piece of plastic mesh that keeps the outdoors where it belongs. As long as your expectations match the price tag, you will likely be satisfied.
Final verdict
Is this 2pcs Round Insect Cover Dustproof Anti-Insect Screen For 130/150mm Air Conditioner Exhaust Duct White Air Conditioner Accessorie review leading to a recommendation? Yes, but with a grain of salt. If you can handle a long wait for shipping and a simple plastic design, these covers are a great way to keep your room bug-free.
They are not going to win any awards for build quality, but they get the job done for a very low cost. I keep mine on all season, and I have not had a single moth fly through my vent since I started using them. For the price of a coffee, it is a small investment that makes a big difference in my summer comfort.
