Great Filter

I have well water I kept having leaks on my copper pipes. Since I put this filter in use. Have not had one in over 4 years. It really takes out the chemicals that eat way at your copper pipes.

Easy to install. I hope it works great!

I just purchased a home with a Hardless filter installed. I ordered the replacement cartridge and post filter direct from Hardless. They included a Jet for easy flushing when I asked (the house had the valve installed, not the Jet). I replaced the old cartridge/filter easily in about 5 minutes. I hope it works good!

Just what we needed!

We put this on as a secondary filter on our well water and it has significantly cleaned it up. Because of the poor quantity of our water, we do need to change it more frequently. But, for us, it is worth it!
