In terms of price, the price of 3M water purifier and filter element is generally higher than that of Aihuipu, with 3M water purifier ranging from 1000 to more than 5,000, and Aihuipu ranging from 7,800 to 3,000, mostly within 2K; Aihuipu's filter cartridges range from 300 to 8900, but the prices are basically within 1000, while the starting price of 3M's filter cartridges is 700,800.
According to some published parameters, the filtration pore size of Aihewlett-Packard is basically only 0.5 micron, while 0.2 micron of 3M is more common, and reverse osmosis pure water machine has a smaller filtration pore size. The water treatment capacity of filter element, Aihuipu's water treatment capacity exceeds at least 1000 liter, and some can even reach 40,000 liters, while the water treatment capacity of 3M is generally above 2,000 liters to 5,000 liters, which means that the filter element replacement frequency of 3M is higher than Aihuipu's, but the filter element of 3M has its own patent.
In addition, in terms of product diversification, the models and functions of 3M water purifiers are much more than that of Aihuipu. There are water purifiers, pure water machines, non-intelligent and intelligent machines. The smart machine has instructions to remind the user to replace the filter element, and the filter element can be used to the extreme and then replaced. Aihewlett-Packard's current products seem to be non-intelligent, so we can only estimate or replace the filter element on our own regularly.
According to my recent understanding and comparison of these two brands, I personally feel that if the economic conditions are average, I can consider buying and loving HP. After all, I need to consider the cost of subsequent investment. If economic conditions permit, I will buy 3M, because it is smart and has many choices, which can meet the needs of different purified water.
Finally, I would like to remind you that there are many fakes that love HP and 3M, including filter elements and PP cotton. If you buy in a physical store, you'd better find an authorized dealer, because some physical stores may be adulterated with genuine products. If you bought it on an e-commerce platform, you'd better see if there is a designated online sales platform for this brand in official website. Don't be greedy for cheap. After all, you can't joke. I hope I can help you.
