How to Choose the Best Whole House Water Filters?

Every house requires a different water filter. Even all the filters taking care of the water supply works in the same pattern, only the addition or lack of filters makes the real difference. 

As you must have noticed, there is a considerable price difference between the three stages and two-stage filters. But, no matter how many filters, you should consider the following factor while browsing for relevant filters. 

Flow of water: 
Whole house filters vary in terms of water flow. As the main water flow has the screen, it will be responsible for the pressure of water in your showers, faucets, and other appliances. Smaller household filters like Home Master HMF2MGCC can produce only 10 000 gallons of water per minute. However, more significant devices like Express Water filter or iSpring WGB32B can do better than that. 

If you have a large family and you are aware that they will consume a lot of water at the same time, especially in the morning hours wherein everyone has to leave for the office, school, or college; purchase a system that has better airflow.

Efficiency of filters depends upon the type of cartridge they are using. So, you should purchase a unit depending upon the water contamination level in your area. For example, carbon block filters are suitable for pesticides, foul smell, and taste. So, if you don’t want to use such water, try to browse filters that have activated carbon filters like Express Water whole house devices. 

Longevity of the filter cartridge:
All the filters need maintenance, and one of the most critical tasks is to replace the cartridges. The lifeline of a filter cartridge depends upon the make and model. Some of the models like Express water whole house filter can filter 100, 000 gallons of water. On the other hand, our sixth contender iSpring WGB21B has cartridges that can be active only up to 50, 000 gallons. Therefore, choose a unit that can match your household usage.
