What is a water filter? 

A water purifier is a machine that cleans and disinfects the water we use and drink by removing contaminants such as germs, bacteria, chemicals, and other impurities. Depending on the filter element, pollutants may be removed in as little as three to six stages of filtering. There are two types of water filters: those that are used and those that are consumed. 

Types of water filters you should know.

1. RO water purifier

Firstly, the most common type of water purifier is the RO water purifier. It is a water filter derived from reverse osmosis that can successfully filter with a filtration of 0.0001 microns. This sort of water purifier has a filtration process that takes 5-6 steps on average.

2. UV system water purifier 

It is a general-purpose water purifier. The filtering system is capable of killing germs but not of eliminating bacteria. If you have a water tank in your house, you should not use a UV water purifier because the water tank is a good breeding ground for bacteria. 

3. UF system water purifier 

Built on UV filters, it’s a water purifier capable of filtering out even the tiniest of microorganisms. Since no pump is used to increase pressure, this type of water purifier saves on electricity costs. No trash is generated through filtration, so it’s best suited for areas with less pollution in the water. However, if you’re going to use it in a distant location, make sure the raw water is of sufficient quality first.

How to choose the right water filter?

When looking for a decent water purifier, consider more than simply pricing and filtering efficiency when making your selection. Because of this, HomeGuru will explain and help you through the process of selecting a basic water filter. 

1. Source of water 

Prior to selecting water filters, it’s critical to examine the quality of the raw water being used for filtration. Sediment content, hardness, chlorine, and brackish water levels will all be varied depending on where you live. For example, water hardness is a prevalent issue in the Northeast, causing scale to form quickly in the kettle. As a result, the water purifier must utilize a resin filter, among other things.

2. Type of water filter

Knowing the water’s condition will help us decide which water filter to use. In addition to varying in filtration performance, filter types also fluctuate in the amount they cost to install and maintain. The filters in particular, as they need to be replaced based on how long they’ve been in use.

3. Size of the water purifier

Another thing to think about is the water filter’s capacity, because the more people it can serve, the more money it will cost. The best water filter to use is one that is related to the members of your family. A small to medium RO water purifier will enough if you simply need to filter drinking water for 3 to 4 persons. Because it minimizes the cost of a water purifier while also using less energy and putting less strain on the filter.

4. Machine specification

Once we’ve decided on a specific model, the next thing to do is It’s critical to pay attention to the machine’s specifics, such as any potential limits. Some RO water purifier creates sluggish water or require electricity to work if waste water is present. As a result, you must first thoroughly research the device’s operation.

5. Budget 

Once you’ve figured out what kind of raw water you’re dealing with and which water purifier to employ, most importantly, it’s time to start thinking about your spending. A RO water purifier costs more than other types of water purifiers because it is more efficient. Prices for filters range from as little as a few hundred baht up to well over a 100,000 baht. 

6. Additional function

The price of a water purifier isn’t solely determined by the model, but also by the function it performs. Starting at roughly 7,000 baht for a RO system that only filters drinking water, but if it also makes tea and coffee, that equipment will cost in the tens of thousands of baht. 

7. Area for installation 

Finally, don’t forget that the filter’s placement space is critical. HomeGuru suggests putting it in a location where it’s easy to get to water and relaxing to use. For the simple reason that if it’s installed too far away from the water source, such as under the sink, it may be subject to additional pipe expenses.
