As we all know, the tap water we use daily contains many impurities, such as sediment, rust, plasticizers, insect eggs, microorganisms, etc., and long-term drinking will harm our health. Secondary pressurized water supply in high-rise buildings can also breed a large number of bacteria in the water tank. In order to ensure the cleanliness and hygiene of drinking water, it is important to use the necessary means to purify the water.
More and more households are using water purifiers to get quality water. The water purifier can filter out most of the impurities in the tap water, and the most advanced RO reverse osmosis water purifier can produce direct drinking pure water, and the purification efficiency is very high. However, the water purifier also has its disadvantages, that is, the unit price is higher, and the cost of replacing the filter element is also high. The price of an RO filter element is often hundreds of thousands of yuan, which makes many users feel a headache.
If the household is not demanding on water quality, it is a good choice to install a pre-filter.
The pre-filter is a kind of filtration equipment installed at the front end of the waterway pipeline, which can filter large particles of impurities such as sediment, rust, and insect eggs in tap water, with a maximum filtration accuracy of 40 microns.
Benefits of using a pre-filter:
1. Extend the life of wading electrical appliances. The pre-filter can filter out large particles of impurities in tap water, reduce the blockage and wear of wading equipment (such as washing machines, dishwashers, water heaters, water purifiers, etc.), and extend their service life.
Problems such as the smaller flow of water in the shower or faucet, the slower heating of the water heater, and the clogging of the filter element of the water purifier can all be solved by installing a pre-filter.
2. Improve the quality of drinking water. Pre-filters can greatly improve water quality and protect the health of your family.
3. Save money. Pre-filters can reduce the failure rate of wading equipment, which in turn reduces the cost of repairs and the expense of replacing equipment. The pre-filter itself is non-replaceable, and the cost of use is very low.
4. Reduce scale. The pre-filter can filter out calcium and magnesium ions in tap water, reducing the formation of scale, thereby reducing the problem of clogged pipes and reduced water heater efficiency.
The pre-filter is used with a water purifier, which can not only purify efficiently, but also prolong the life of the filter element.
Introducing a few pre-filters with a good reputation and affordable prices:
1、霍尼韦尔（Honeywell）PFF20T12-EC：
Honeywell is a well-known electrical brand in the United States and a Fortune 500 company, with reliable quality. This pre-filter uses copper head with lead isolation process, and a food-grade isolation layer is added inside to avoid the precipitation of heavy metals after water and copper contact, and fully protect the health of water quality. Three-in-one self-cleaning, forward + siphon + double-sided scraping to ensure that the filter screen is not clogged for long-term use. Antifreeze and explosion-proof filter bottle, 316 stainless steel strainer, durable.
It can filter 7 tons of tap water per hour without affecting the water output speed. The filtration accuracy is 40 microns, and large particles, insect eggs, sediment, rust and some microorganisms can be filtered out. With different sizes of fittings, it is suitable for all types of water pipes.
2. Haier pre-filter HP-05:
This Haier pre-filter has been on the Jingdong Gold List and is a star item. The copper head also adopts the lead isolation process to avoid the precipitation of heavy metals. It can filter 7 tons of tap water per hour. The self-cleaning is also very powerful, and it can reverse the 360-degree pressurization to flush the filter and scrape, and it will not clog after long-term use. Double-layer 316 stainless mesh filter, 40 micron filtration accuracy, life-long replacement-free. Anti-freeze and explosion-proof filter bottles.
There is a memory ring on the top to record the time of each filter flush, which is convenient for regular maintenance.
3、美的（Midea）QZBW20S-12T：
This Midea pre-filter also adopts a lead isolation process to avoid the precipitation of heavy metals and harm to health. Filtration accuracy 40 microns. 316L stainless steel double-layer filter, life-long replacement-free. Twin turbine forward and reverse flushing + scraping, long-term use of the filter screen will not clog. It can filter 7 tons of tap water per hour, and the water pressure does not decrease. Anti-freeze and explosion-proof filter bottles. There is a water pressure gauge on the top to monitor the water pressure in real time. There is a self-cleaning recording ring.
4. WHEELTON WHT-P0038:
The copper tip of this pre-filter uses a lead isolation process to prevent heavy metal precipitation and affect health. It can be automatically backwashed + scraped to keep the filter screen from clogging. Integrated PPR joints are used on both sides to eliminate potential water leakage. 316L stainless steel strainer with a filtration accuracy of 40 microns. It can filter 6 tons of tap water per hour.
When the water flows through, it creates a high-speed swirl that prevents impurities from adhering to the filter screen, avoiding clogging and reducing the water flow. There is a water pressure gauge and a memory disc on the top. Anti-freeze and explosion-proof filter bottles.
Summary: The pre-filter can improve the water quality from the source, effectively protect the water appliances, improve the quality of drinking water, and is very practical. Compared with the large cost of using a water purifier, it is still very cost-effective to spend a few hundred yuan to solve the water quality problem.
