That’s why it is prudent to use a water filtration system to ensure your family drinks safe water.

But you need to consider where you need to purify your water first because we have different filtration systems for different scenarios. Also, go for systems that are NSF-certified because that means they have been thoroughly (and independently) tested and proven to remove the said contaminants.

Questions to ask when looking for a good water filter
Let’s look at some of the most frequently asked questions regarding the best home water filter system to choose.
- How much water do you need to be filtered? If you are looking for a filter for purifying only your drinking water, then you will be ok with the slow filters. But if you are looking to filter lots of water, you want one that is fast and efficient.
- Where do you want to use the filter? Do you want a portable filter for outdoor use? Or are you looking for one to be mounted on your faucet/under the sink for home use only?
- What contaminants do you need to remove? If a water filter is designed to remove germs, there is a good chance that it will not be effective in removing chemicals. Do not assume that any water filter is suited for all kinds of contaminants. You can search the water filter in the NSF database to see what it has been certified to remove from drinking water.
- What is the cost of the filter? Water purification systems can cost anything from a couple of bucks to hundreds or even thousands of dollars. But the most important cost factor is not just the purchase but the installation and maintenance costs involved. Beware of inexpensive filters that might cost you way more in maintenance.
