I have been buying filters for my home ventilation system for a few years now.
When I first looked at the amount of parts available on the web shop I thought it was going to be difficult to find the right part for my machine. It turned out it was a lot easier than I thought. Moreover I can always look at my previous purchases and order the correct part every time making the whole process very quick.
Strengths
Broad inventory, super quick delivery and great customer service!
