Aquasafe RO/DI?

[PoonTang]

I believe they say at a usage rate of 2-3 gal per day the filters last about a year.

I have one and it's pretty good, the fittings are an adventure to set up to not leak, use lots of Teflon. The unit itself works great though, easy to get cartriges as well. As for the price, when i got mine there was 2 options, one came with all the needed media, the other came with a bunch extra for a few changes.

Using a Aquasafe for about 5 years. Removed the post carbon filter, replaced my membrane once, try to replace my pre-filters about every 6 months and DI lasts about a year. Other maintenance is replaced the ASOV a couple of times and one check valve.

Not including water changes due evap use about 2 gpd. No leaks and I'm happy with it.
