Review on Sunsun Original Replacement Accessories Canister 🔍 Filter: Enhance Your Filtering System with Quality Replacements by Megan Smith

I gave 5 stars as it is exactly what it says it is. Ordered after reading the questions. Someone said it matches the 404B filter I have. I was so excited when it arrived! I ran straight there to change everything to find that it actually does NOT fit the 404B. The check valve is the wrong size and when I tried to connect the tubing to my old check valve, the tubing was too small. It took my husband and I about an hour to heat up the tube and slide it over my old check valve so it stretched enough to fit. I had to use metal hose clamps and it was very frustrating to say the least. Not the sellers fault as the listing does not indicate this applies to the 404B. So I will not lower his rating because of my mistake. But for those looking for one for their 404B, this isn't it.
