WaterDrop Under Sink Stainless Steel Water Filter As13 Review

Product Overview

When I wanted to improve my kitchen's water quality, the WaterDrop Under Sink Stainless Steel Water Filter As13 stood out. As someone who relies on tap water for drinking and cooking, I needed something unobtrusive yet effective. The As13's direct-flow under-sink design keeps counters clear and targets chlorine, taste, and odor. Its stainless steel build and NSF/ANSI 42 certification made it seem ideal for daily use. I was especially curious about its long-term performance, maintenance, and whether installation would be as simple as claimed. Here's my review after several weeks of daily use.

Key Features & Technology

• •Stainless steel housing is durable, modern, and resists corrosion, making it a solid under-sink fixture.
• •NSF/ANSI 42 certification ensures reduction of chlorine, taste, and odor, which I noticed immediately.
• •Direct-flow design delivers filtered water instantly-no waiting for tanks.
• •Damage-free installation kit avoids drilling, perfect for renters or anyone wanting a reversible setup.

Performance Testing Results

Right away, I noticed a big improvement in the taste and smell of my tap water. Coffee and tea tasted cleaner, and the chlorine aftertaste was gone. The flow rate stayed steady, easily filling pots or glasses without delay. I used the filter for both cold and hot water, and it handled typical kitchen tasks without any drop in pressure-even with the dishwasher running. The filtered water had no metallic aftertaste, which I've encountered with some stainless steel filters. While I can't test for every contaminant, the difference in taste and odor was obvious. The filter performed reliably during heavy use, with no leaks or strange noises. For daily drinking, cooking, and rinsing produce, the As13 consistently outperformed my old pitcher filter.

Installation Experience

Installing the As13 took about 40 minutes, mainly due to tight under-sink space. The kit included all necessary fittings and clear instructions. I appreciated not needing to drill, which is great for renters. The quick-connect fittings attached securely to my cold water line, and the stainless steel body felt sturdy as I mounted it. I needed a wrench for a couple of connections, but nothing was difficult. If your plumbing is older or unusual, you might need an extra adapter, but for most kitchens, installation is straightforward. Measure your space first, especially if you have a garbage disposal or other appliances under the sink.

Daily Use & Maintenance

Maintenance has been simple. The stainless steel exterior wipes clean easily, and there's no plastic to crack or discolor. The filter cartridge is quick to replace-I practiced swapping it out and it took less than a minute. There's an indicator to signal when it's time for a new cartridge, so there's no guesswork. I haven't reached the end of the filter's life yet, but expect several months between changes based on my use. No flushing or messy backwashing is needed. The system doesn't require electricity or complicated upkeep-just periodic filter changes. For busy households, this low-maintenance approach is a real advantage.
