OWYR Adjustable Magnetic Fly Screens (up to 131x150cm) – DIY magnetic strip window insect net in white frame/white mesh
Product description
The essentials
If your windows seem to invite flies, mosquitoes and other small insects in at the worst possible times, a fitted window fly screen is one of those practical fixes that doesn’t need a full makeover. The OWYR Adjustable Magnetic Fly Screens are designed to sit on the window frame using magnetic strips, with a mesh panel you can trim down to fit smaller windows. It’s a straightforward DIY approach that aims to keep air and light coming through, while helping block insects.
On paper, this product leans towards a convenient “measure, trim if needed, stick, done” solution. It’s also made for everyday home use—especially useful if you’ve got kids or pets—and it’s positioned as a fairly flexible option across different window styles and frame materials.
Key features worth focusing on
Adjustable size and DIY trimming

The screen is intended to fit windows up to 131x150cm. If your window is smaller, the mesh can be trimmed to size. That flexibility matters in real life, because window openings rarely match a stock size perfectly.
Do note a small limitation: the window screen size may vary by 1–3cm, which means you might need some minor trimming for a truly snug fit. If you’re expecting an exact “no cutting ever” situation, you may want to double-check your measurements before ordering.
Magnetic strip fit with fewer gaps


A key idea here is the magnetic fly screen window strips. The goal is a secure fit with fewer gaps where insects could slip through. This is particularly relevant if you’ve used cheaper screens before and found edges that don’t quite sit flush.
Fibreglass mesh with fire-resistant positioning

The mesh is described as flame-retardant, fireproof, and chemical-resistant, and it’s made as a fibreglass window netting. That’s a reassuring set of claims for a product you’ll have near living areas where cooking happens, but as with any “safety” wording, it’s still sensible to follow the intended installation and care instructions.
What it’s actually like to use
In day-to-day use, the main benefit is the trade-off: you keep fresh air and sunlight, while the mesh barrier works to reduce insect entry. Imagine opening the lounge window in the evening to cool the room, while the mesh sits in place so you’re not swatting every few minutes.
The installation approach is also geared for convenience. It uses strong adhesive for a no-drill setup and is described as taking around 15 minutes, leaving no marks on the frames. That makes it appealing if you rent, or if you simply don’t want to drill into window frames.
The mesh is washable and replaceable, and cleaning can be done with a damp cloth or vacuum. That’s the kind of practical maintenance detail you’ll care about once dust and pollen start building up.

Where it fits best (and where it may not)


This OWYR screen is described as broadly compatible: it works with aluminium, wood and iron window frames, and it’s said to suit sliding windows, casement windows, shutters, skylights, bathroom/toilet windows, plus caravans or balconies.
It makes the most sense if you’re after an insect screen that can be installed without drilling, and you want the flexibility to trim to match your specific window.
It may not suit you as well if you need a perfectly exact fit with no trimming at all, or if your window frame conditions mean adhesive mounting is not practical. Also, while magnetic strips are meant to reduce gaps, the final seal still depends on how closely it sits once fitted—so it’s worth planning your measure-and-cut carefully.

Is it worth it?
A solid pick if you want a DIY window insect screen that blocks mosquitoes and other insects while keeping air and light, and you’re happy to measure and possibly trim the mesh for a snug fit. The adhesive/no-drill approach is especially attractive if you want minimal fuss and no marks on the frame.
You may want to skip it if you’re expecting a perfectly exact fit out of the box for your specific window size (without trimming), or if you can’t use adhesive mounting on your window frames. In that case, it might be better to look for options that match your window measurements more rigidly.


Mini FAQ

How quickly can it be installed?
The listing describes installation as taking around 15 minutes using adhesive with no drilling, and it includes a step-by-step installation video.
Can the mesh be cut down for smaller windows?
Yes. The fly screen can be trimmed to fit smaller sizes than the maximum 131x150cm.
Will it work on different window frame materials?

It’s described as working with aluminium, wood and iron window frames.
Is the mesh easy to clean?
It’s washable and replaceable, and you can clean it with a damp cloth or vacuum.
What keeps insects out—mesh or magnets?
Both play a role: the mesh acts as the barrier, while magnetic fly screen strips are intended to help the screen sit securely with fewer gaps.
