Good system, slow shipping

I bought the Whole House Water Filter and was pretty happy with the installation process; the instructions were clear enough for me to do it myself. The water quality improved noticeably, especially for showering. My only real gripe was the shipping time. It took 8 days to reach my place in Texas, which felt a bit long when I was eager to get it set up. Customer service was helpful when I called about the tracking, though.

Great value on Under Sink

I was looking for a good deal on an Under Sink Water Filter and found HomeWater during a seasonal sale. The price was competitive, and with the discount, it felt like a real saving. I was a first-time buyer so I appreciated finding a quality system that didn't break the bank. The water tastes so much better now. For the money, it was definitely worth it.

What's the deal with returns? If I get a system and it's not what I expected, is it a huge hassle to send back?

L Lisa 2 months ago

I returned a wrong size sediment filter last month, no issues. Just followed the instructions on their site. Got my refund pretty quick.

I Ivy Carter 2 months ago

I think it depends on the item. For the big systems, there's probably more to it, but for smaller stuff like replacement filters, it was super easy for me. Check their policy for the specifics on whole-house systems though, just to be sure.

Anyone know if you can use more than one discount code? Trying to stack a first-time buyer deal with a subscription one.

S Steve 2 months ago

Nah, usually you can only use one code at a time with most online stores. I tried with a different promo and it didn't work.

R Renee 2 months ago

From what I remember when I signed up, you can't stack codes. The subscription discount is kind of its own thing, like a permanent price cut. You get that just for signing up for auto-refills.

Are these guys legit? Like, the filters actually work as advertised or is it just fancy marketing?

T Tara R. 2 months ago

I've had their under-sink for about 6 months, and the water tastes way better. Before, my coffee was kinda weird. Now it's solid.

R Raj G. 2 months ago

They're legit. I did some research and they have NSF certs for their filters, which is a good sign. My plumber actually recommended them over a few other brands.

Hey, thinking about getting a whole house system. Do they ship to Alaska? Seems like some places don't.

N Nina 3 months ago

Yeah they do! I'm in Anchorage and got my order pretty fast, like a week or so.

B Beth 2 months ago

They totally ship to AK and HI, I remember seeing it on their site when I was checking out. Might just take a little longer though.

How do these compare to Aquasana? I'm torn between the two for a whole house system and can't decide.

B Beth S. 2 months ago

I had an Aquasana before this and switched to HomeWater. The installation was a bit smoother with HomeWater for me, and I feel like the filter life is pretty comparable. Water quality seems just as good.

W Wendy W. 2 months ago

My buddy uses Aquasana and is happy, but I went with HomeWater mainly because of the pricing during a sale and the filter replacement cost seemed a little less long-term. Both are solid options though, can't really go wrong.
