Under sink water filter – The Buyer’s Guide

Although the above section might’ve helped you find the right under sink water filter for your needs, if you’re still confused, continue reading this. We’ve discussed various factors that you should consider when getting one.

1. Your Requirements vs the Features

Make sure that the under sink water filter you are getting has all the features you are looking for. Because, I believe that there’s no point in buying it, if it can’t do the main task you’re buying it for?

  • The Most Feature Rich: iSpring RCC7AK, NSF Certified, 6-Stage Superb Taste High Capacity Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization-Natural pH, White
  • Average Features (But High Value for Money): EcoPure Main Faucet Under Sink Inline Water Filtration System (EPWUFF1) | NSF Certified | Reduces Chlorine, Sediment & Cysts | No Additional Faucet Required
  • Cheap Yet Feature Rich: 2 x Replacement Under Sink Filter Cartridges 6 Month for all Undersink Systems

2. Pricing vs Budget

Wouldn’t everyone buy the most expensive or the best under sink water filter if it wasn’t for the budget? Although the best option has a lot of extra features, I personally believe that you should not overspend on the product for the features you won’t use.

However, a lot of us have limited budgets and in some cases you might end up sacrificing an important feature. In such a case, don’t sacrifice. Because if it can’t perform/do the main task for which you are buying it, is there any point in getting that?

3. Brand

Although, branded under sink water filter costs a little more than the unbranded options. But I advise my readers (including you), to consider getting the one from a reputed brand. Not only do they offer great customer service, high-quality build, and global support, but they’re also easy to re-sell and fetch a better price despite being old.

4. Check out the Best Lists

One of the best ways to find good quality under sink water filter is by browsing or checking out the best lists like this. The writers/researchers do huge research and make sure that you get the best-quality product with features suited for diversified tasks. Although, in some cases, the lists won’t be great, in that case, just check out other lists.

5. Look for Deals

You can either use the deal finder on our website or look for popular deal websites. In some cases, you can save upto 5-15%. However, in this case, I’ve already listed out the options with links to the best available deals. Also, make sure that you’re getting from an authorized seller (there’s a huge increase in online fraud).

6. User Reviews

One of the best things about buying a under sink water filter online is, there are a plethora of eCommerce platforms that have “customer reviews” where a person who has bought the product reviews it and shares his/her experience with it. You can also check for a specific feature in those sections and you’ll surely find a lot of answers.

7. Individual Product Reviews

Individual product reviews are written by bloggers, independent reviewers, researchers, media publications, etc where they review and test the product for weeks and publish an in-depth review about that single product. You can just make a Google search and you’ll find endless individual under sink water filter reviews.

The Best under sink water filter Brands in the UK

Like mentioned above, buying a branded under sink water filter can save you from troubles in the future with high-quality customer support and could also fetch a better resale value. According to me, here are the best-rated brands you should consider:
