SpectraPure® MicroTec Sediment Filter Cartridge - 0.5 Micron - 10"

I've been a user of SpectraPure RO units for over 30 years. I bought my first one when I lived in a town with hard, bad-tasting tap water. I had been using a bottled water service, but switched to the RO when bottled water became more costly than gasoline (at the time).

I also keep aquariums, and my favorite fish species tend to be from soft water environments, so I use a 10 gallon pressure tank and blend the RO water with tap to get my desired hardness..

SpectraPure branded filters and cartridges have always worked well for me. There are cheaper alternatives available, but SpectraPure's product performance is consistant and I tend to stay with a brand that I KNOW will work. I can normally get a year's use from the filters/cartridges, and I've only had to change-out a membrane once.

SpectraPure is a small company, so at times their processes can be a little slow and item availability kinda sketchy, but they always come through.

I'm currently on my 3rd SpectraPure RO (90 GPD / Non-DI) in my 3rd house. If I ever move again, I will buy another.

I guess that makes me a satisfied customer.
