Things to consider before buying Best Countertop Water Filter

Whether you are installing Counter top water purifier in your kitchen or in your office, anyone looking to buy a countertop water filter want to take following factor into consideration.

  • Price

The first thing that hits you when searching for a Countertop water filter is the price. As long as you get a quality water filter you are ready to pay good amount of price for it.

But that doesn’t mean you are ready to take risk of inexpensive countertop water filter because you know quality products cost reasonable price.

Ever thought how much could a reasonable countertop water filter cost you? You need to spend an amount of 100$ to 200$ for average water filter.

You can pay couple of dollars more to get additional features like smart counter top water purifier which can signal you if needs repair.  Size and design matters too.

  • Length and Width

After knowing the price, you’d like to check the countertop size. You can’t simply purchase a countertop filter without knowing if you can place it in your kitchen shelf. Incase your countertop water filter size is bigger then your washbasin size. You need to hold in hand that’s quite uncomfortable.

An average dimension of perfect countertop water filter is between 11*5*11 inch to 18*17*8 inch. You can choose the size according to your space.

Also you don’t need a huge space to keep the countertop wash basin. But you need to adjust according to space of the countertop. 

For example if you want to install them in the counter wash basin there the space is less you must choose the dimension accordingly.

Whereas in countertop kitchens there is more space available. 

  • Weight of water filter

This can be stupid question but many people want to know about the weight of water filter. The average weight can be around 3 to 6 pounds. 

Therefore you can safely keep the countertop purifier in your washbasin safely without straining or breaking.

  • Filtration

Not all water filter works equally same. Some water filter will remove contaminants like chlorine from water whereas some cannot.

Some filters remove essential minerals like Calcium and magnesium which are required by our body. They turn the water into crystal clear. This inturn gives acidic taste to the water.

Check your water source and the TDS using, any TDS detecter out there. If the TDS level is more then 500 you are free to use them. 

Check the Latest Price:

If your TDS is below 500 you must go for purifier which will remineralize your water. The purifier model will retain the essential minerals and remove only unwanted minerals.

  • Alkaline nature of water

Try to use water filter with filter cartridges to make your drinking water more effective. But Why? This is because Alkaline water is good for skin, hair, boosts your immune system and promotes weight loss.

You would definitely get pure and clean water but wouldn’t say NO if you get extra benefit in your drinking water.

  • Maintenance of filter

Different filters need different type of maintenance. There are 2 types of filters:-

Ceramic filter and Carbon filter.

Ceramic filters can last long but you must clean them alternate days. People say Carbon filters don’t last long but I believe that inorder to improve its life you must check the source of water because more impurities can ruin your filter’s life and need maintenance.

Also keep a track of the flow of water. If the water flow is irregular and abnormal, the water filter may need maintenance.

These are beginner recommendations before you buy the Best Countertop water filter. As a result you are aware that you must not go for a cheap quality water filter.
