Customer Reviews
Decent filter, delivery kinda slow
Ordered the HIS Under Sink Water Filter last week, was super excited to get it hooked up. Installation was pretty straightforward, and the water tastes really clean, definitely an upgrade from my old Brita. My only real gripe is that delivery took a bit longer than I expected, especially since I signed up for the newsletter hoping to catch a quick promo code. Still, good quality product.
So happy with my Doulton filters!
just got my taste fresh under sink filter last week and the water tastes amazing!!! it was super easy to install, even replacing my old brita filter setup. i was worried about compatibility but it fit perfectly. already told my neighbor to check them out, definitely shopping here again, especially if i catch a newsletter promo code next time!
so close to perfect!
anyone else love their gravity filter spigots?! got a couple replacements and they're fantastic, way better than my old brita filter. the water tastes amazing, like seriously pure. only tiny thing is i wish they'd send out those newsletter codes a bit more often, but i'll definitely be back for more filters and telling everyone!
amazing filters, way better than brita!
wow, the ultra fluoride filter candle is incredible, removes so much stuff for just about 20 bucks, definitely shopping again!
Decent, but a bit slow
Thinking about getting a Doulton filter? I picked up the HCP Countertop Water Filter recently and setup was pretty straightforward. The water tastes great, definitely better than plain tap, and I like not having to mess with pitchers like Brita or ZeroWater anymore. My main gripe is that shipping took a little longer than I expected. I was hoping to get it sooner, especially since I've been eyeing these for a while. It's a solid filter, just be prepared for a bit of a wait.
duo filter review
yesterday, the duo under sink filter arrived late, but product seems solid.
solid water filter
grabbed the HIS Under Sink Water Filter, shipping was quick and install kit helped a ton.
solid filter, worth the newsletter signup
got a decent 15% off my HCS Countertop Water Filter by signing up for their newsletter, which was a nice bonus at checkout. install was super straightforward, literally took me like 10 minutes to get it running. the water quality is noticeably better than my old Brita pitcher, no weird tastes or smells anymore. only thing is, i wish they made it clearer about the return policy on the product pages itself, had to dig a bit to find it. but overall, really happy with the purchase and planning to grab some replacement filters soon.
Good filter, shipping was okay
I bought the SuperSterasyl Filter Candle for my system. It arrived well-packaged and was easy to swap out. The water tastes noticeably cleaner, which was the main goal. Shipping took about 6 days, a bit longer than I hoped, but still within their stated window for the US. Customer service was responsive when I had a question about installation, even if the information was already on the website.
Quick delivery, good product
Ordered an Ultra Fluoride Filter Candle. It shipped fast and arrived in perfect condition. Easy to install myself. Happy with the purchase.

Hey, thinking about grabbing a gravity filter system but wondering about shipping time to like, California. Anyone ordered to the US recently and can share how long it took?
