For sash windows

RESPILON® Adjustable Screen is designed to fit every vertical or horizontal sash (single/double hung) window. Four modifications fit this range:

height (METRIC)width (METRIC)height (IMPERIAL)width (IMPERIAL)
26 cm 46–84 cm 10” 18–33”
38 cm 51–94 cm 15” 20–37”
50 cm 75–140 cm
60 cm 85–160 cm

Two screens = Best airflow

Smog season is heavy during winter, so there is usually no need to use RESPILON® Adjustable Screens in summer.

When in use during summer, there can be more demand for airflow. Airflow can be greatly increased, by placing two RESPILON® Adjustable Screens in windows situated opposite to each other. Thanks to the “chimney effect” your interior will always have plenty of fresh air while being effectively protected.

Independent test results TÜV SÜD

To further proof unique characteristics of our product we present you a test results from TÜV independent testing of our filtration media. Upper table contains particle concentrations before lower part after and bottom row are corresponding efficiencies. Most important is PM2.5 - 97% filtration, PM1 - 91%.

Why nano matters?

There are more ways to do a filtration media. Some producers use enectrostatically charged medium to artifficially improve filtration capabilities and airflow. This works great but for very limited time. It obviously discharges quite fast in outdoor aplication. On the other way nanomaterial is just so dense that it purely mechanically blocks what it shoud. Can't be discharged just slowly cloged (see maintanance). Nano is what matters, it makes the product really work and two outer layers serve as a protection and structural support.
