The Lemmens filters from WTW-filtersOnline
HRV filtersOnline is the place to be for the best Lemmens filters. Our filters are a perfect match for your HRV unit. This way you can enjoy a good and healthy indoor climate without any concerns. Of course, the filters are polluted after prolonged use. It is always smart to replace your Lemmens filters on time. This is best done every six months, but we recommend checking every 2 months to see if the filters may need to be replaced early. If the filters are white or light gray, this is not necessary. Darker or even black would actually be too late. This way you are always assured that your uni functions optimally.
