Although Philips is a Fortune 500 brand with a history of more than 120 years, in the course of more than 120 years, water purification is not the main business of Philips, or even a small branch of its diversified business. Compared with some foreign brands that are "not adaptable", Philips claims that its water purifiers are "tailor-made for Chinese consumers", and from the perspective of product materials and filtration schemes, Philips' water purifiers are indeed more down-to-earth.

The product line of Philips pre-filter is not complicated, and the more noteworthy ones are AWP9812/AWP9815 and WP4100/00. The appearance of the AWP9812 is silver, which looks more fashionable, because it uses a stainless steel valve body, stainless steel is absolutely lead-free, so it is safer than other brass products, and can eliminate lead pollution, and the price is about 1,000 yuan.

And its performance is quite decent, 40 micron filtration precision, 316 stainless steel filter screen are the industry average, 2.6 tons of water per hour is barely enough, but only direct flushing function, the flushing effect is definitely not as good as backwashing.

The AWP9815 is an upgraded version of 9812, the difference is that there are more voltage regulators, and the water pressure can be adjusted according to actual needs, and the price is about 1500.

The WP4100/00 is imported from Germany, using German brass body, 40 micron filter, with backwashing function, 2.3 tons per hour flow rate is slightly lower but sufficient, the overall product performance is OK, the price is about 1,000 yuan.

In terms of installation and installation, the general door-to-door installation is free, if it is too far away from the outlet, you need to charge a certain remote fee, the material is practical and real, it is recommended to ask the price before purchasing.
