Factors to Look for in an Under-Sink Filter System
With so many products in the market, what factors should you keep in mind when purchasing a
- Type of filter: When it comes to a filter, there are multiple variables you should consider. First, buy a system whose filter has been extensively tested and certified according to industry standards. Second, consider longevity. Some under-sink filters last only a few months, whereas others can last for years. Third, consider the cost of replacing the filter or whether the filter is even replaceable.
- Dimensions: Before you fork over hundreds of dollars for a filtration system, consider the space you have beside/under your sink. Some filtration systems can be very cumbersome, and you might not have the space to install them.
- Installation procedure and cost: Some filtration systems are made to be extremely easy to install, and you can install them on your own. Others will require you to call a plumber, which will incur extra costs. Another thing to consider here is whether the system has permanent/semi-permanent installation. If you are currently living in a rented house, you will have to go for a system that offers non-permanent installation.
- Maintenance cost: Filtration systems are not maintenance free. In most cases, you will need to call a plumber to take care of the maintenance. Even if you learn to DIY, you still have to consider the time costs. When buying a system, find out how often it needs maintenance.
