DuoClean Pre Filters and Post Filters for Colorfullife XPSTFH380 Review

The product page for these filters lists the Shark UV850 as one of the compatible vacuums. These filters are not suitable for UV850. The original filters (dirty in the picture) have a different length than width. The Colorfullife filters are the same size on all four sides. These filters are the same thickness as the original filters so they might fit if they do indeed fit your vacuum cleaner, but they don't fit the UV850 and the seller doesn't need to say what it does.

Great product. I need a replacement for my rear filters which to be honest I don't change regularly. I found these and the fryer, after reading the reviews I decided to give it a try. They arrived quickly and as described. I even started changing filters a little more often and saw a huge difference in how my back was functioning. In particular, it helps a lot that these filters can be used. They're easy to clean, although it may seem like an eternity for all the dirt to clear the filters, but…

I can't confirm how well they work as real filters but they fit my Shark perfectly and it works great with these filters. Mine were about two years old and you can only clean them so many times that you just want to replace them. At this price I have a feeling I'll be replacing them more often because I use my vacuum a lot and have pets so the stuff I clean is pretty messy. I'll update my review if anything changes, but this time I'm happy with the product and glad I found a cheaper version…
