ᐅ Replacement filters for central residential ventilation systems made of coarse filter fleece, G2–G4 ratings

Hello everyone,

I was frustrated by the high prices of replacement filters made of coarse filter fleece for the exhaust air valves of my ventilation unit (Vaillant recovair) and now produce these myself in high quality and at relatively low cost, as well as other diameters for systems from Helios, Viessmann, Lunos, or Pluggit (110 mm (4.3 inches), 125 mm (4.9 inches), 135 mm (5.3 inches), 140 mm (5.5 inches)) in filter classes G2, G3, and G4.

Selling through platforms like Amazon in sets of 10 is quite expensive, as about 30 - 40% goes to fees and shipping, so I have to add that to the price. I would prefer to offer the filters in larger quantities and pass on the cost benefits as much as possible, meaning under one euro per piece in any case.

Would anyone be interested if, for example, sets of 100 pieces or more were offered? I’m still unsure which sales channel would work best. I could, of course, use the Amazon platform but handle the shipping myself, which would then result in only about 15% fees plus regular parcel shipping costs.

Looking forward to your feedback.

What exactly do you mean by "comparatively inexpensive"? For example, your selling price for 100 pieces of DN125 G3?

1. A filter in G4 class, for example, only costs about €1.5–1.8 each when buying a pack of 10.
2. I also make my own filters – just buy the mat and cut it yourself.

You have to be unbeatable on price then. Go ahead.

Currently, I can offer €0.95 per piece, meaning a set of 100 would cost €95 plus shipping (I estimate the package shipping around €5). Once I sell larger quantities, it becomes worthwhile to upgrade the stamping process, which would initially bring the price down to about €0.60 - €0.70 per piece.

Even with G4, depending on the size, I can currently offer prices between €0.70 and €0.95 per piece for larger quantities (e.g., 100). As mentioned above, after a small investment in equipment, I can reduce this by another 20% quite easily.

You can currently get it for just 80 cents?!
