Ventilation Grille Filter Cover Nasta Polet (S) with Allergen Filter and Insulation
Product Details
Simply attach this over your existing indoor ventilation cover to block dust, pollen, and other particles from entering.
- The pollen removal filter removes approximately 80% of dust and pollen. (Removes over 90% of cedar pollen.)
- To replace the pollen removal filter, simply remove the cover and peel off the filter inside.
- It features an opening/closing function that allows you to prevent wind from blowing in during strong winds, such as during typhoons, by simply removing the cover and reattaching it upside down.
- The sound-absorbing and heat-insulating material is a component that is attached to improve insulation and reduce external noise.
? Please purchase gypsum board pins separately.
? The filter is dirty.
? It was attached to the wall and removed, so a small amount of wallpaper remains on the back.
