SpectraPure® CSPDI System Cartridge Replacement Kit - Standard Twist On Cap - FK-CSPDI

Filters came in quickly and were a great replacement for my worn out filters. Will be buying again in a year or so

Refreshing the filters has certainly restored the performance of my RODI system. It's so much faster than it was when the filters were at the end of their usefulness.

SpectraPure shipped the replacements quickly which was helpful.

I had to replace my RODI membrane and cartridges in my 90 gallon per day unit. Received order in a timely fashion and it only took about 30 minutes to replace them all. Let the unit run for a couple of hours and got perfect readings on my TDS meter which were 0 ppt. Thank you Spectrapure

I love my spectra pure filter unit. Ive had it for some time and it's done a fantastic job at keeping my reef clean, i recently purchased the replacement filters and am confident it will continue to do it's job. Great products

I have been using SoectraPure RO/DI filters for almost 20 years. They work extremely well for purifying the water for my salt water fish tank.
They are easy to contact and provide refills promptly.
