Love these filters. Easy to breathe through, last ages before having to discard. Recommend (although I have moved onto the Lanaco masks now :-)
HELIX.iso™ Filters - Standard Protection
I discovered these filters last year when buying cloth masks. It came to my attention the mask seller was supporting was making a nice mark up on selling the filters so I decided to look direct at the manufacturer. Love these filters - easy to handle and fit to cloth masks and very functional. The older filters I had did appear thicker slightly and I am assuming the product has been improved from what I purchased quite sometime ago. Delighted with prompt delivery and tracking - certainly won’t be paying the inflated prices some ‘on sellers’ are marketing. Recommended:-)
Of all the mask + filter combos I've tried, this is by far the best. I feel safer and can breathe easily.
found it rather hot and sweaty compared to the paper type.
