The cheapest Itho filter
Replace filters? Then of course you don't want to pay too much for that. Fortunately, we at WTW-filtersOnline are the cheapest provider of filters. In addition, we also offer the cheapest volume discount so that you never pay too much. This can be as high as 20%! This way you can already save filters in case they need to be replaced. Do you actually know how often filters need to be replaced? Many people do not know this or forget to replace the filter regularly.
Regularly checking your ITho filter can save you a lot of trouble. Dirty filters cause poor air flow and in some cases can cause the HRV unit to overheat. This can be another fire hazard. Therefore, make sure to check the filters every 2 months. You usually have to replace the ITho filter every six months, but in some cases this will also have to be done earlier. This depends entirely on the amount that the HRV unit is used.
