Guardian Filtration Products 2 Pack - New Spa Filter Cartridges Fit: UNICEL 6CH-47-FILBUR FC-0315-Pleatco PTL47W-P4

Keeps our spa nice and clean. these filters are always a pain the neck to clean and don't seem to work as well after a cleaning.

We use these filters in our hot tub. They work great. I clean them by soaking them in a 5 gallon bucket with some bleach in the water. Then I take a pressure hose to clean them. They last longer that way and I don't have to replace them as often. I am a repeat buyer.

exact substitute.

It hard finding the right size of filter but this was a decent value and work well.

I ordered two filters both with the same part number and two different filters arrived. Both filters are not marked with any part numbers or brand which makes me dubious about the actual brand. The green filter started fading within three days. Also the green one appears to be made of a different inferior filter material, is shorter than the blue one, and has what appears to be a detachable thread.. What is going on guys!?*Update #1* Contacted seller and they said they have changed their "molds" and are now sending out the green and blue filters until the blue ones are out of inventory. They said that the filter material was exactly the same which is false. They told me to return what I purchased and gave me no option to purchase and receive just a blue filter so I'm stuck with mismatched filters.*Update #2* Ordered a two pack of blue filters and while in the transit process the listing was updated to the green filters and that is what I received two green junk filters. I contacted Amazon who said to find another seller and they would contact the seller to let them know of the complaint.

Used in hot tub. Perfect fit and delivered within 24 hours.

I ordered a pack of 2 filters. They stacked them on TOP of each other. If you are familiar with these filters the TOP has a bow shaped handle for installation and removal. STACKING the threaded end on top of this handle causes the threads to get destroyed.UPDATE: The full amount was refunded and the sellers communication throughout the ordeal was actually really good. I still don't have the filters I need and I hope they have a conversation with the packaging folks so this doesn't happen again.

Does a great job for our hot tub. We can't find this size at any pool stores but Amazon always has them in stock

Good deal and a fast delivery!

Exactly as they should be, very good.
