Outstanding Filtration: Waterdrop TSA Under Sink Water Filter System
I recently installed the Waterdrop TSA Under Sink Water Filter System, and it has exceeded my expectations in every way. This 3-stage high-capacity water filtration system delivers pure, great-tasting water right from my kitchen sink, making it a fantastic addition to my home. Installation was straightforward, thanks to the detailed instructions and included hardware. Even with minimal DIY experience, I was able to set it up without any issues. The compact design fits neatly under the sink, taking up minimal space, which is a big plus for those with limited cabinet room. The filtration performance is exceptional. The 3-stage system effectively removes chlorine, heavy metals, and other contaminants, leaving the water clean and safe to drink. The improvement in taste and clarity is noticeable immediately. It’s reassuring to know that my family is drinking high-quality water without any harmful impurities. One of the standout features is the high-capacity filters. They last a long time before needing replacement, making the system low-maintenance and cost-effective in the long run. The easy twist-and-lock design of the filter cartridges makes changing them a breeze, further enhancing the user experience. Additionally, the water flow rate is impressive. There is no noticeable drop in pressure, even with the filtration system in place, which is often a concern with other water filters. Overall, the Waterdrop TSA Under Sink Water Filter System is a top-tier product that provides excellent filtration, ease of installation, and long-term cost savings. It’s an investment in health and convenience that I highly recommend to anyone looking to improve their home’s water quality.

Water filter
The filter was easy to fit and does a good job of removing odour and taste leaving crystal clean good tasting water. Only drawback is the reduction in water flow rate. I worked through this with Becky from Waterdrop, who was incredibly helpful and responsive. Overall a good product, I have had it fitted for a month now and happy with the purchase.

Great Product, cheaper Price
5-Star Review I recently purchased the Waterdrop TSU 0.01μm Ultra-Filtration Under Sink Water Filter System, and I couldn’t be happier with the product! Easy Installation: The installation process was quick and straightforward, with clear instructions that made setup a breeze. No special tools or professional help were needed – I had it up and running in no time. Great Design: The sleek and compact design fits perfectly under the sink without taking up too much space. The smart panel is a fantastic touch, providing real-time filter status and ensuring I always know when it’s time for maintenance. Excellent Water Quality: I conducted a water test before and after installation, and the results were impressive. This system effectively filters out impurities while maintaining beneficial minerals, providing crisp, clean, and refreshing water. No Waste Water & Long-Lasting: I appreciate that this system produces no wastewater, making it both eco-friendly and efficient. With a 2-year lifespan, it offers long-term value and peace of mind. Overall, the Waterdrop TSU is a top-notch under-sink water filter system. If you’re looking for easy installation, exceptional design, and outstanding water quality, this is the perfect choice. Highly recommend!

Lovely tasting water
I have had the single Waterdrop under sink kit for the last couple of years due to living in a rural area and the water company in Pembrokeshire often over chlorinating the water. When the filter needed changing this time I upgraded to the three filter version which also came with its own very solid little separate tap for filtered water. The whole system was easy to fit, with no leeks but took my wife and I about a half an hour or so because we both struggle with aging knees and backs! Well worth doing yourself though as the setup is clearly explained and very well labled. Initially, the first day we had an issue with water taste, however after contacting Kimberly a Customer Service Rep at Waterdrop she quickly identified the issue and remedied it straight away by sending out a replacement PP filter which arrived the following day and took literally 5 seconds to swap over, (water is now very similar to expensive bottled water!) Kimberly is an excellent customer service rep, she is a credit to Waterdrop and I will definitely buy more of their products in the future, great product, great customer service!

Taste good but it doesn't filter the limescale
Tastes good, smells good, and is very convenient to have it fitted this way. We have been using Brita for many years, and it worked well, but we wanted something else to help save space in the kitchen. The only downside for us is that it does not filter limescale.

Doesn't filter limescale
I used to use filter jugs and I purchased this hoping to see results but it doesn't filter the most visible element which is limescale. Who knows if it actually gets rid of other things that this filter claims it filters. My kettle if full of lime scale as if it has been filled up with unfiltered water. Water pressure has also dropped significantly. The only good thing is easy installation and the size of the product as it can be fitted under your sinc with little space.
