If you landed here, you know that under sink water filtration doesn't come cheap. What you may not know, is how many companies discount their under sink water filters around holiday.
Yes, just like the TVs and the toaster ovens, these filtration systems go on sale. As long as you can get in before the rush, there's no better time of the year to pick up your new system.
For the last month, we've been watching deals pop up on under sink water filters and ranking them based on the discounts and the quality of the filter. Below you'll find the best of them, from top to bottom.

#1 Best Deal: CuZn UC-200 Under Counter Water Filter
From simplicity to value, this model struck all the right notes this holiday
All of these filters say they're "easy to install" but if you've ever tried installing one yourself (as a layperson I mean) you know that's not often the case.
The CuZn UC-200 is different in this respect. It connects directly to your cold water line under the counter and... that's it. You don't have to drill through the counter to connect anything else up top. You can tell when you compare it visually to the other models its smaller, more compact, and simpler, and the experience of using it is exactly the same.
Why else is the CuZn UC-200 worth getting?
- 5 year lifespan per filter: It's rare to see a lifespan this long on a filter of this price.
- Look at the reviews: That is a perfect rating from thousands of customers. I review a lot of products on Amazon and I've almost never seen this.
The only reasons not to get this filter are if you intend to use it for a water supply other than municipal water, if you want it to soften the water as well (it won't) or if you want to reduce TDS (filter nerds, you know what I'm talking about.) This is not a reverse osmosis filter.
For everyone else? Have at it. The CuZn UC-200 Under Counter Water Filter is a great filter at a great price.
#2 Best Reverse Osmosis Deal: APEC 5 Stage RO Water Filter System
It's a jump up in price, but the additional filtration capacity and features of the APEC 5 Stage filter more than justify the price. It's also more steeply reduced than the CuZn filter.
Yes, it'll take a little more effort to install. This model comes with its own faucet, so you'll be connecting up parts both above and below the counter. But for the extra work come extra rewards, and big ones.
This filter will reduce Total Dissolved Solids. It will remove odors and unpleasant tastes. It removes 99% of more than 1000 different contaminants. And best of all, it won't reduce your water pressure (feeding water at 45-80psi).
The performance of this APEC Water Filter is second to none at this reduced price. If you get the chance to pick up this filter on sale, you'll be mighty glad about it.
#3 Best Budget Filter Deal: Water Drop Under Sink Filter
If even the CuZn in our #1 spot was more than you had wanted to spend, I've got you covered. This under sink filter from Waterdrop is high performing, highly rated, and really cheap.
The Waterdrop under sink filter does well reducing the biggest baddies: The lead, copper, chlorine and rust in your water supply. But - unlike the reverse osmosis filter in our #2 spot - it keeps the potassium, calcium and magnesium (salts your body actually uses) in.
Like the Cuzn model, the Waterdrop has an extremely simple installation, no faucet to fiddle with, and a quick filter replacement process. The company claims, and a number of customers have verified that filters on this model can be replaced in as little as 3 seconds!
On the downside, the filter life is only 2 years compared to 5 years on the CuZn, so you have to weigh the short-term costs against the long-term costs here.
Overall, the Waterdrop Under Sink Filter is one of the only bargain under sink filters that really performs.
#4 Best Splurge: Waterdrop 7 Stage Tankless RO System
Say you want perfection in an under-sink filter: Filtering the most contaminants with the most convenience. If that's you, you want the new Tankless reverse osmosis system from Waterdrop.
Not only does it offer the best filtration performance of any model on our list. It has been lab-tested to death and meets multiple NSF certifications (not just NSF 42 like cheaper filters). It reduces Total Dissolved Solids. It removes limescale (no more descaling your kettle!). You can't think up a contaminant that this thing doesn't remove.
... but it's small. The filters sit vertically in one box and the whole thing is only 5.6 inches wide! If you don't want to lose storage space under your sink, this is the only model that can help.
A final benefit (and this is only understood by people with reverse osmosis systems already): With the Waterdrop Tankless system you don't have to wait for your water after turning on the tap. Thanks to an internal pump, the system can produce a cup of pure clean water in just 12 seconds.
Again, if you want it all from an under sink water filter and you're willing to invest to get it, the Waterdrop Tankless system is for you.
#5 Biggest Price Reduction: Aquasana 3 Stage Water Filter
Aquasana is a trusted name in at-home water filtration and this year they happened to have the biggest % price reduction on any under sink model we found. It's a heck of a filter too.
Performance-wise, this filter is better than the CuZn, and the first Waterdrop model but not as good as the Apec RO filter at #2. Why is it worth paying more for then?
Well, not being a reverse osmosis system it's simpler to install. It works on well water or city water, which is only true of this deal on the list. And it has iPhone app connectivity to measure gallons produces to help alert you when a filter change is required. Cool if you're into that kind of thing!
If you want a high performing system and you love a big deal, the Aquasana 3 Stage Water Filter is the filter to pick.
