OWYR Magnetic Fly Screens for Windows Fit Max 151x180cm (DIY adjustable magnetic window net) – White frame, grey mesh

If you’re trying to stop flies and mosquitoes getting in while still letting air and daylight through, a magnetic fly screen is one of those ideas that sounds simple until you try it with real windows. This OWYR magnetic window net is designed to be adjustable, trim-to-fit, and installable without drilling.

That “no-drill + magnetic strips” combination is exactly why people look at this type of product. It’s also worth keeping expectations realistic: if your window opening isn’t close to the stated range, or if fitting requires very precise trimming, it may feel a bit fiddly.

Key takeaways

On paper, the OWYR magnetic fly screen is built for practical everyday use: it’s adjustable to fit windows up to 151x180cm, uses magnetic fly screen window strips for a secure hold, and it’s made with a fiberglass mesh described as flame-retardant, fireproof, and chemical-resistant. You get an installation video and it’s held in place using strong adhesive so you can set it up quickly and leave no marks on the frame.

It’s mainly aimed at households that want to keep insects out without permanently changing their windows—particularly places where kids and pets roam, but you still want to ventilate rooms.

What you’ll notice in day-to-day use

This screen’s job is to keep insects out while allowing fresh air and sunlight in. In practical terms, that means you’re not stuck relying on a closed window or a ceiling fan setup just to reduce mosquito risk.

The magnetic strips are the bit that typically makes these screens feel “easier” once installed: they help the screen sit more securely and reduce the chances of gaps compared with purely loose mesh. And because the mesh is described as washable and replaceable, you’re not left with a one-season consumable—at least, that’s the intent.

Still, note that the window screen size may vary by 1–3 cm and “minor trimming may be required” for a totally neat fit. If you’re expecting an out-of-the-box fit on the first attempt with zero adjustments, you may be disappointed.

Where it shines (and where it doesn’t)

This is a strong fit if you want: - A DIY window fly screen that doesn’t involve drilling or leaving marks - Adjustable sizing so you can trim it to a smaller window opening - Compatibility across a fairly broad set of window types, including sliding windows and casement windows - A mesh intended to be flame-retardant/fireproof and resistant to chemicals (as stated in the description)

It may not be the best choice if you have an unusual window shape where trimming won’t help much, or if you’re not comfortable doing light DIY work with measurement and trimming. Also, if you’re aiming for a “perfectly invisible” finish, the white frame and grey mesh are what you’ll get—subtle, but still noticeable.

Installation and getting the most from it

The pitch here is pretty clear: quick installation in about 15 minutes using strong adhesive, with no drilling and no marks on the frame. On the practical side, that usually means you’ll want to plan your measurements carefully before trimming.

A micro-example: if you’re fitting this in a bedroom where the window opening is slightly narrower than the max size, you’d typically measure the clear opening, mark the screen for trimming, cut neatly, then position the frame so the magnetic strips line up where the window closes. After that, you should get the everyday benefit—open the window for airflow without inviting insects in.

Pros

• Adjustable, trim-to-fit design for windows up to 151x180cm
• Magnetic strips aimed at keeping the screen secure and reducing gaps
• No drilling and no marks on the frame (adhesive-based setup)
• Fiberglass mesh is described as flame-retardant/fireproof and chemical-resistant
• Washable and replaceable mesh, plus easy cleaning with a damp cloth or vacuum
• Broad compatibility across common window frame materials and several window types

When it makes sense?

Buy the OWYR Magnetic Fly Screens for Windows Fit Max 151x180cm if you want a DIY insect screen that prioritises quick installation, no-drill mounting, and airflow-friendly use—especially if you’re dealing with mosquitoes and insects while keeping windows open.

It’s not for you if your window opening is far outside the stated range, you don’t want to trim/adjust for a neat fit, or you’re expecting a completely gap-free result with zero measuring effort.

As a final sanity check before you buy, double-check your window size against the max 151x180cm figure and remember the description mentions minor size variance (1–3 cm) may mean trimming is required.
