(Updated 5/10/19) Time to change out filters on this countertop unit. But I have to say: I've been getting nearly weekly emails from this co. since my original purchase about a year ago. "Half off", or "Oops, we sent you a huge discount by mistake, but we'll still honor it" or "We've extended our discount for one more day"..etc..etc.. If you order direct from their website, its actually a few bucks more than through Amazon. I paid $64.71 originally through Amazon. If I follow the email spam for "half off", I'm directed to their website, where they show the original price at nearly double, and with the "half off" promo, it drops down to anywhere from $65 to $90 bucks! In fact, as of today, I can buy the exact same entire unit for $57.13, OR I can buy JUST the replacement filters for $59.99!? Huh?? I feel like Aquasana is more of a marketing company than a water filtration company. Which sucks, because I really like the unit I bought! The water tastes good, install was a breeze, but given all the "bait and switch" slick marketing campaigns going on, I'm much less confident! Why are your prices SO different? Why not just offer the same item at nearly the same price across all of your seller platforms? Give or take a few bucks. I understand that Amazon might take a cut of your sales, but ordering through your own website should be just a tad less expensive? It makes me think the focus is more on marketing and web clicks, and less on good quality products. Now, that said, should I buy 2 replacement filters for $59.99, or just toss my entire current unit, plastic housing, metal fittings and tubes in the trash and buy a whole new unit for $57.21? I'm not an extreme environmentalist, but this just seems silly!! Unit arrived on time, with my prime 2 day order. Everything was present, all parts accounted for. I had to buy an adaptor from home depot, for about 8 bucks (It's the taller chrome one on the right) , as the 2 they included were not long enough to fit in my faucet. No big deal there. Install was a breeze, once I got everything tightened down, using a bit of Teflon tape. Ran for 10 minutes as instructed. After that, just good clean water. Vegas tap water has some funky taste, but this definitely passed my taste test. Almost like soft water. Only thing is, it flows slow. Not a HUGE deal, but worth noting. I timed 2 minutes to fill a 3qt container. My workaround for that is, I spent several minutes filling up my 5 gal upside-down water jugs, and placed them on my dispenser. As my pic depicts, I zip tied the tubes along the faucet so I have full swivel ability, and no kinks. Last noteworthy thing, I emailed the company to inquire how many gallons do they recommend before changing out the filters. 2 days later, I have not gotten a response. (Week days) After actually reading thru the pamphlet included, I saw it was 450 gallons. My fault, but still, I'd hoped the customer care response would come within a 24hr period or so. Let's hope I get something soon? Overall I give 4.5. If this thing goes good, I'll consider a shower unit as well.
