AQUA CRESTNSF, TÜV SÜD Certified Maxtra Refill Catridge, Reduces Lead, Arsenic and More, Compatible with Brita Mavea Maxtra, Maxtra, 105731, 1001122 (Pack of 6, Packing May Vary)

I bought these to use in my Maeva Maxtra pitcher. The Maeva filters I’ve bought via Amazon in the wake of Maeva’s exit from the US market haven’t been that great — the taste of chemicals in my tap water becomes noticeable when the filter is still registering at 40-50%.In contrast, these Aquacrest filters work well all the way through a cycle. The price is fantastic. I’m on my third Aquacrest filter and am very pleased. Great product!

The water runs thru the filter much slower than the factory filters. I believe it is because the manufacturer uses lower quality materials so the water has to run slower to be properly filtered. I did test the water and it removed what I could test for. The water tastes the same. That is ok because my water tastes fine.

Comes in an unmarked box, not as shown on the picture. Instruction, package or cartridge has no Aqua Crest label. Instruction poorly translated with lot of grammar mistakes. I don’t consider this safe for my family and if, who knows what the fakers put into it. You can read about faked cartridges stopped at the border.

This doesnt seem to be a very good substitute for the original mavea filter. Unlike the mavea you have to soak it and then run a few pitchers of water through it first. More importantly, water runs right through this filter like it isnt even there. I keep checking the seal and it seems to be sealed. No way to know for sure but to me it doesnt seem to be filtering much at all. I guess there's a reason it cheaper than the original.

The water runs through these so fast that I don’t think they are filtering the water as well as the mavea brand filters. The water doesn’t taste as well either. They are inexpensive but I will spend more to get the brand name next time I order.
