Tap water is used by every household now, but what is different from before is the concept of water safety. When we were young, we could only boil water with well water. Now that technology has advanced, many people think that drinking tap water directly is harmful to health. So is it necessary to install a water purifier if you have tap water at home? Today’s article will help you understand it thoroughly!
First, let’s look at the process required by the water plant to deliver water to our homes.
It can be clearly seen in the picture that the tap water entering the home has to go through a long process of storage and transportation in the tap water pipeline, so there will inevitably be impurities in it. Especially for high-rise residents or old communities, the tap water is secondary water supply . However, we have had tap water in our homes for a long time. In the past, it was okay for so many people to drink directly. Why is it now advertised that water purifiers must be installed before drinking?
In fact, the main visible impurities in tap water are heavy metals or sediment and rust. You can drink it by boiling it directly, but the taste may not be very good. The function of a water purifier is to block these impurities and turn tap water into soft water, making it taste better when you drink it. This is very reassuring for people who are pursuing a high-quality life.
So if you really need to buy a water purifier, which type is better to choose (no ads)
1, pre-filter
The pre-filter is installed before and after the water meter, filtering various impurities through the filter. This kind of filter
not only makes drinking water safer, but also protects household appliances involving water in the whole house, such as toilets, showers, water heaters, etc., reduces scale corrosion on shower faucets, and extends the service life of washing machines and toilets. There are three main points to consider when purchasing a
pre-filter: (1) Filtration accuracy > 40 microns (2) Water flow rate ≥ 4T/H (3) Automatic flushing
Installation location: Generally installed at the front end of the water pipe entering the house. If installed indoors, it is recommended to install it at the kitchen sink, which is more convenient for draining.
2, direct drinking water purifier
The more popular nowadays is the RO reverse osmosis water purifier. In comparison, it has the highest filtration accuracy and the highest safety factor. For direct drinking, it is better to choose RO reverse osmosis membrane.
Key points to consider when purchasing: (1) water flux is greater than 600G (2) purified water flow rate is > 1.5L/min
Even though a water purifier is installed, it does not mean that everything is fine. The filter element must be replaced in time, otherwise it is safer to boil the tap water and drink it. Generally, if your home has a PP cotton filter element, the replacement cycle is 3-6 months, and the RO membrane reverse osmosis filter element can be replaced in up to 5 years. It depends on the requirements of the brand you choose.
Seeing this, I believe you should have a clear understanding of whether to install a water purifier. Do you think it is necessary to install a water purifier for tap water? If given the choice, would you rather drink boiled tap water directly or purified soft water ?
