Buying Guide: How to Buy an Under Sink Water Filter
When choosing an under-sink water filter, the different models available in stores as well as online would make it a bit difficult for you to decide. But with this buying guide, it will help you make the right decision.
Some models have a design that grabs the attention of customers, but it shouldn’t be the first thing that you should look for when choosing the right unit. The following are essential factors to consider when buying an under-sink water filter.
High-quality filters usually last for years. Make sure that the model you choose has a long lifespan, so you won’t need to change the filters immediately. Among the best ways for you to know if the filters have a long lifespan is to read customer reviews. The quality of the filter also depends on the materials, which manufacturers use. Only buy a model from a manufacturer and store that you trust.
You have a lot of options when it comes to the type of filters. Among the options that you have, there are models with pre-filters or a UV filter. You can choose the simple type if you want an easy installation process. Some classes require you to buy a faucet while other models include it in the package. If you choose a model that is difficult to install, you would have to hire a professional plumber.
If you want your water to be free from contaminants, you have to buy more filters. Some models have three filters, while others have more, and it requires a larger space. Some models are quite expensive due to the quality of materials or components and the number of filters it has. But such models ensure the safety of the water that you use. If you have the budget, then a higher price might not be a problem.
Size and Under-sink Space
Any filter that you choose should fit in the space in your under-sink. If there’s limited space, consider having a model with smaller filters. You can have the standard type, but you can also choose to buy additional filters. Consider your budget and prepare for a bigger space if you want more filters. You can even choose to renovate the kitchen sink.
It is for your benefit to check if the unit is easy to install. If you want to save your budget, then choose a model that you can manage to install without a plumber’s help. For beginners, make sure to follow the manual without missing a step so that you won’t damage the unit. You can watch videos on how to install the device if you have difficulty in following the manual.
But if you choose to buy additional filters, it is better to ask for help from a professional plumber. Some models that have a separate filter for the faucet involve drilling. And if you have no idea how to do it or you lack tools, then ask for help though you have to pay for an installation fee.
Before buying an under-sink water filter, check if the model has good water pressure. It should quickly fill the glass or any container that you want to fill with water. When you compare these water filters with the conventional type, the former has better water pressure.
Make sure that your water source is free from contaminants. An increased water pressure won’t be able to block the contaminants entirely from entering the filter. It is one of the downsides of choosing a model with increased water pressure.
The model that you should choose should be of high quality so that it can last for a long time. Frequently changing the filters only means that you have to spend more money. If the performance of the filters drops, then you have to look for new filters.
You can check the manual on how to change the filters. And before buying the model of your choice, consider the price and availability of the unit. Finally, it must be easy to clean and replace of your under sink water filter when needed.
The use of high-quality components makes a water filter last not only for a few months but for years. If you are tired of replacing your under-sink water filters, check if all of the components are of high quality before purchasing the unit. Although the price is higher when you compare to other models, the maintenance cost would be low.
