When I first moved into my house nearly a decade ago, the first thing I did was get a reverse osmosis filter system for my drinking water. After a few years of dealing with the slow trickle of a tanked system, however, I upgraded to a Waterdrop Filter tankless RO system, and it was the best decision I ever made.

Now, you can pick up one of Waterdrop's best-in-class RO water filtration systems at the lowest price of the year!

Waterdrop makes fantastic tankless RO systems and countertop water filters, and three of the brand's best models have deep discounts for Prime Big Deal Days.

The star of the show is the flagship Waterdrop Filter X12, which has a huge discount right now. Use the coupon code BGRreader at checkout, and you can get this $1,200 model for just $854.05!

Another great deal is available on the Waterdrop K6, which is the only model of its kind that has instant hot water on demand. It retails for $799, but it's down to $474.05 using the same promo code, BGRreader.

And finally, the Waterdrop CoreRO that sits on your countertop instead of being installed under your sink is down to just $189.05 instead of $299 when you use the code BGRreader at checkout.
