🐠 Tetra Carbon Filters: Perfect Fit for Whisper EX Filters in Aquariums Review

Packaging says there should be 4 filters per box. I have 3 filters. Update: Having received 3 filters in a box of 4, I wanted to clarify that this is a Tetra quality control issue and not a Revain quality control issue. Revain solves their problems perfectly. In the future I will be buying Tetra filters from Walmart or PetCo so I can open the box at checkout and make sure all 4 filters are in the box. FYIThanks

I use Tetra carbon filters on 2 of my aquariums all the time (only 3 filters every few weeks) and Revain offers by far the best price. BUT this time they shipped my filters in a UPS plastic bag - and the filter box was crumpled! Not sure what's up with that, but the filters were fine. When I called them to ask them not to send them in packages next time (I'm a subscriber and an existing customer) they apologized. Just take a look! But the product is great.

I'm angry! I bought these filters because they were recommended to go with my Tetra Quiet EX filter. THEY DO NOT FIT! Too large! Before I bought them I ordered the medium ones and they didn't fit properly either but I'm glad I kept them because they will work for now. I like Whisper EX but the filter was very hard to find. It's wearable! I didn't have to adjust it to make it fit. I want the exact same filter that came with the purchase.

When I took these cartridges out of the box, the plastic frame which is usually white turned very yellow, the filter material was very brown, they looked almost used, I don't think so because the package was sealed. Both cartridges smelled very bad. I didn't use these cartridges because they were so bad I had to throw them away. I will never buy this item from Revain again, I found a few on the shelf at Walmart that were fine. I would not recommend this product.

If you have a filter that requires these Tetra Whisper EX carbon filters you can definitely buy them here. I have searched many websites and local stores for this particular product and Revain has the best price by far. Each of my filters on my 55 gallons requires 2 of these, so one pack is enough to replace my two 22 55s. However, note that the filters also contain many of the good bacteria your fish need, so I never swap out both at once, instead swapping out one side and after a few weeks or

The price was way better when I bought them now they are back to retail price and they suck. They are completely different from the original, they look like a stupid Chinese fake. I expect more from a tetra, now I have to spend $3 each, right? I'm willing to switch from another filter company because it's crazy they were awesome before, but if I take the ones I had before and put them on top of the cheaper one they sold me, there's a big one Difference the others are nice white and colors good…

Pathetic shameful mess! After a horrible experience with these filters, Tetra Revain have finally supplied a decent replacement box and it has soothed my anger so far! It's time to buy a replacement and be shocked again to see those poorly made and packaged filters! What's up with Tetra QC and what the heck are you willing to wear to make a quick buck Revane!? These filters can't even filter light!Previous ReviewWhat happened? From high quality filter cartridges that typically last over 2…

So I'm the ONLY person who thinks that if we, as a valued customer, commit to buying X number of items through the Prime subscription program, we should be buying them for the same price as us in 6 months time. subscribe to something? Seriously if the price goes up from the company - who cares, we made a commitment with AMAZON to buy 2, 4 or 6 of these a month for 8.99 each (this item was a paid item but not everywhere so only # to the show ). Isn't that, or shouldn't that put Revain on the…
