Spring Cleaning for Your Water: Best Waterdrop Filters to Upgrade Your Tap Water

Every spring, people deep-clean their homes, clearing out closets, swapping heavy curtains for lighter ones, packing away the blankets, and more. But one thing most households completely forget to refresh is the water coming out of their taps. If you’re already in reset mode, it might also be time to give your drinking water an upgrade.

Founded in 2015, Waterdrop Filter is a leading brand in home water purification. And during its Spring Sale, you can get your hands on its most popular RO systems with discounts of up to 30%. Whether you’re a renter on a budget or a homeowner ready to go all-in on water quality, Waterdrop Filter has something in its lineup for you. Here’s what you need to know.

Waterdrop Filter G3P800 Tankless RO System – Best for medium to large families

The G3P800 is Waterdrop’s best-selling under-sink RO system, for good reason. At 800 gallons per day, it’s got enough output for medium to large families. And the tankless design frees up 50–70% of under-sink space compared to traditional bulky tank systems, so you lose out on a large chunk of valuable cabinet space.

Filtration is, of course, the highlight of the G3P800. The NSF/ANSI 42, 53, 58, and 372-certified filter features ten stages of precision RO filtration and a built-in UV sterilizing light to keep contaminants like PFAS, heavy metals, and Chlorine in check. It reduces PFOA by 98% and PFOS by 99%, with more than 99% lead reduction, which matters a lot if you live in an older home.

Until March 31, you can get the Waterdrop Filter G3P800 for just $699, a $300 discount, making it one of the better value picks in the RO market right now.

Waterdrop Filter X12 RO System – The flagship, ideal for large households

If you want to go a step further, the X12 is Waterdrop’s flagship under-sink system. It pushes 1,200 gallons per day, is fast enough for even the busiest households, and runs 11 stages of filtration. What sets it apart from the G3P800, though, is the mineral-rich output. Rather than stripping everything out, the X12 adds beneficial minerals like calcium and magnesium back into the water, making it taste sweeter and more pleasant, while also enhancing the flavor for cooking, making tea, or brewing coffee.

Contaminant reduction numbers are unsurprisingly excellent. The X12 is capable of 98.88% PFOA reduction, 98.97% PFOS, and more than 99.87% lead reduction. It’s particularly well-suited to families with babies or elderly members who need consistently clean, great-tasting water for formula, tea, and everyday cooking.

During Waterdrop Filter’s Spring Sale, which runs till March 31, the price of the X12 drops from $1,299 to $899.

Waterdrop Filter DLG-P: Ideal for renters

If you don’t want to commit to a full RO system or are renting a place where installations might be a problem, Waterdrop Filter has you covered with the DLG-P. This budget-friendly under-sink option is designed with renters and first-timers in mind. Installation takes just three minutes, and filter replacement a few seconds. No plumber required.

The standout feature here is the two-outlet design. It includes a dedicated filtered faucet, separate from your main tap, making it a practical setup for everyday kitchen use. PFAS reduction is still impressive (99.7% PFOA and 99.6% PFOS), and a smart filter life indicator takes the guesswork out of knowing when to replace the cartridge.

During Waterdrop Filter’s Spring Sale, you can get the DLG-P for just $99.99 ($20 discount), giving you access to clean water even if you’re on a tight budget.

Waterdrop Filter TSU: The entry-level water filter system

Rounding out the lineup is the TSU Ultrafiltration system, the entry-level pick with a compelling eco angle. Unlike RO systems, the TSU produces no wastewater and doesn’t require electricity to operate. It uses 0.01-micron ultrafiltration to remove 99.9% of bacteria, along with heavy metals like lead, chlorine, fluoride, and sediment. Crucially, it retains the natural minerals in your water, so you get a cleaner taste without the full mineral-stripping process of RO.

The TSU is compact, saves up to 70% of under-sink space, and offers an impressive 24-month filter lifespan, keeping ongoing costs low. If you want a no-fuss upgrade that’s kinder to the environment, this one is worth a look.

Until March 31, Waterdrop Filter is reducing the price of the TSU from $189.99 to $139.99, a 26% discount.
