Fits into a standard insect screen frame
Buy it by the roll and fit it into your existing insect screen frame yourself, or have your screen maker fit it.
The Odera window filter is a three-layer nanofiber membrane fitted in place of an insect screen. It lets air through and stops dust, pollen and insects smaller than mosquitoes from getting in.
A three-layer nanofiber window filter: air flows in, while dust, pollen and tiny insects stay outside.
The holes in a standard insect mesh are small enough for flies and mosquitoes but far too large for particles such as dust, pollen and soot. So every time you open the window, dust comes in with the outside air: the windowsill darkens, furniture gets dusty quickly and pollen season brings constant sneezing. Most of us end up closing the window, and the home gets stuffy.
The window filter was developed to end this dilemma. It looks like an insect screen and fits in the same place, but its nanofiber layer lets air through while holding back dust and pollen. So you can leave your window open with peace of mind.
See what arrives at your door: a filter made to fit your window, hook-and-loop tapes and a small stapler. With the roll model, a ready-cut filter to fit into your screen frame.




Air passes through the filter; dust, pollen, smoke and insects stay outside. See this in the animation on the left and the layers in the diagram on the right.
Particles stay in the filter, air passes through.

Smoke, dust, allergens and spores stay in the nanofiber membrane.
The filter’s strength comes from its layered structure. The outer mesh protects the membrane, the nanofiber membrane in the middle holds back particles, and the inner mesh carries the whole structure. Nanofiber is a web of fibres much finer than a human hair; its pores are small enough to hold back dust and pollen yet numerous enough to let air through.

The breathable outer layer. It withstands sun and weather, protects the membrane and keeps its shape after cutting.

The breathable inner layer that carries the filter and gives it strength. It stands up to washing and daily use.

Buy it by the roll and fit it into your standard insect screen frame yourself, or have your screen maker fit it. If you choose the hook-and-loop model, you need no special tools or installer: we prepare the filter to your measurements and send it with the hook-and-loop tape, and you simply stick the tape to the frame and press the filter on.

Measure your window frame; if you bought a roll, cut the filter with scissors, leaving a little extra at the edges.

Clean and dry the frame, then stick the self-adhesive hook-and-loop tape around it.

Starting from the top edge, press the filter onto the tape and straighten the corners.

That’s it. When you want to clean it, peel the filter off the tape and rinse it.
For step-by-step instructions and things to watch out for, see the installation guide.

A window filter is a three-layer nanofiber membrane fitted to windows and doors like an insect screen. It lets air through and stops dust, pollen and tiny insects from getting in. It is also known as a new-generation insect screen, dustproof insect screen or pollen screen.
Yes. The filter is designed to filter the air, not to block it. With the window open the room keeps airing. Like any filter it slows the airflow a little; in windy weather you will hardly notice, while on very still days the room may take a little longer to air than with an ordinary screen.
The holes in an ordinary insect mesh are small for flies and mosquitoes but large for dust and pollen. The nanofiber layer in the middle of the window filter also holds back fine particles in the air. You can find a detailed comparison on the window filter vs insect screen page.
A window filter reduces the amount of pollen that gets in while the window is open. This makes opening the window, and especially airing the bedroom, more comfortable in pollen season. The filter is not a treatment; continue your allergy treatment with your doctor.
Yes. As well as flies and mosquitoes, it keeps out tiny insects such as sand flies that can pass through an ordinary insect mesh.
Not for the hook-and-loop model; scissors and a clean surface are enough. You can fit the roll model into your existing screen frame yourself; if you need a new frame, your screen maker can help.
Yes. Take the filter off and rinse it with lukewarm water from the outer side towards the inner side. Do not scrub it, and do not use detergent, bleach or a washing machine; refit it once it is dry.
A filter that is fitted correctly and cleaned regularly lasts for years. It is made from materials that withstand sun and weather. If airflow drops noticeably despite washing, or if it tears, we recommend replacing it.
