The filters are standard size. So I think that any filter will work, but I am sure that there will always be filters available since it is made by Honeywell.

I too have the AquaSafe RO/DI system I purchased on eBay. it is a great system. My dad even purchased one a couple months after I did. So far I have only used it for drinking water and the ice maker, but plan to use it for my new saltwater take I'll be setting up starting next week.

As for filters, it uses standard 10" filters that can be purchased from AquaSafe or hundreds on on-line sites. You can also find them at your local Lowe's or Home Depot. RO filters (the RO membrane part) usually last about 5-6 years. They can be replaced, but at the low prices you can get systems on eBay for, it's probably just as cheap to buy a whole new system in 5 years or so.

I've had mine running for 8 months now and have not needed to change the filters. I purchase a TDS meter when I bought the system and tap tested at around 200 TDS, filtered water went down to 0 TDS with a fews days after installing the new system. It is still in the 0 - 5 TDS range, so there is no plan to change the filters at the moment. I'm sure the new saltwater tank will take it's toll on the filters and I will need to change them soon.

The AquaSafe is a great system at a great price. Most of the systems are basically the same, so it really doesn't matter which one you buy, just get a good price. AquaSafe offered a good install manual and FAQ, with some good humor thrown in. I recommend the company and the system.

I think 1-2 years (depending on tap water quality) is a much more probable estimate.

Oh and welcome to AA

It depends on water quality and the amount of water you run through it. Obviously, the more water you filter (bigger aquarium) the less time the membrane will last. Some of the filter systems, AquaSafe I know for sure, have a valve that when switched over allows you to "back-flush" the membrane periodically. This extends the life of the membrane.

Another thing that will extend the life of the membrane is good quality pre-filters. Most systems have 3 filtration steps before the membrane. Keeping these pre-filters changed on a regular basis will extend the life of the RO membrane as well. I don't think 5 years is an unrealistic time frame at all.

I own a Kinetico 3 stage RO filter, it has an automatic TDS meter that actually tells you when the cartridges are exhausted and the TDS increase. If you go to their website, they have a ten gallon storage tank for larger families. I use that and its perfect for my 30 gallon tank.
