Who Should Buy This

This Waterdrop NSF 42 Certified Water Filter is perfect for anyone who uses PUR® faucet filtration systems and wants a reliable replacement filter. It is great for families or individuals who care about clean and safe drinking water. The 6-count pack offers good value and lasts up to 18 months, so it is ideal for those who want to save money and avoid frequent filter changes. If you like fast shipping and convenience, this product is a smart choice because it is Prime eligible.

However, this product is not for people who do not have a compatible PUR® faucet filtration system. If your faucet filter brand is different, this may not fit or work properly. Also, if you only need one filter and do not want to buy a 6-pack, you might want to look for a smaller quantity option. Lastly, if you prefer filters certified for removing more contaminants than NSF 42 covers, you may want to consider other filters.

Our Testing Experience

First Impressions

When I first got the Waterdrop NSF 42 Certified Water Filter, I was excited to try it out since it promised cleaner, fresher water straight from my faucet. The package included six filters, which felt like a great value for the price. Installing it on my PUR® faucet filtration system was pretty straightforward. The size was just right, not too big or bulky, fitting perfectly without any hassle. Right away, I noticed the filter felt sturdy and well-made, which gave me confidence that it would do a good job.

Daily Use

Using the filter daily was simple and convenient. Every morning, I poured water straight from the faucet and was happy to taste the difference immediately. The usual chlorine taste and smell were gone, and the water felt much fresher and cleaner. It really made a difference, especially when drinking plain water or making tea. I liked that the filter worked quietly and didn’t slow down the water flow much, so it wasn’t annoying to use at all.

Key Features in Action

The most impressive part was how well it reduced chlorine, taste, and odor, as promised by its NSF certification. The water tasted noticeably better, which made me want to drink more throughout the day. I also appreciated that the filter was made from lead-free material, which made me feel safer about the water quality. Even though it doesn’t reduce total dissolved solids (TDS), I didn’t find that to be an issue for my everyday drinking water needs. Knowing it’s tested and certified gave me peace of mind about the filter’s effectiveness.

Long-Term Performance

After using the filter for a few months, I was still very pleased with its performance. The water quality stayed consistent, with no drop in taste or clarity. The filter lasted the full 3 months as advertised, and swapping in a new one was easy and quick. Having six filters in the pack meant I didn’t have to worry about running out anytime soon. Overall, it proved to be a reliable and cost-effective way to keep my tap water tasting fresh and clean over time.
