In the cold winter, heating brings us warmth, but have you ever wondered whether the warm air blowing into the room is clean? Tiny pollutants like dust, bacteria, pollen and more may be sneaking into your home! Don't worry, the "invisible guardian" in the heating system, the junior high efficiency filter, is silently guarding your respiratory health.
Primary filter (like large mesh screen) Material: coarse fiber mesh or metal mesh task: block large particles (dust, hair, catkins, etc.) ≥5 microns to prevent them from clogging heating pipes or damaging equipment, like "blocking large rocks" for the system. Medium effect filter (like fine mesh screen) material: synthetic fiber or electrostatic material task: capture 1-5 microns of tiny particles (pollen, mold spores, some bacteria), further purify the air, for efficient filtration "decompression". High efficiency filter (like the filter under the microscope) material: ultrafine glass fiber or special membrane material task: intercept ≥0.3 micron PM2.5, viruses, bacteria, etc., filtration efficiency of up to 99.97%, called "air purification elite"
"Health guards" in heating: How do filters work? Scenario 1: Underfloor heating system Underfloor heating relies on air circulation to take away heat, but dust is easy to accumulate on the heat exchanger, reducing the heating efficiency. The primary effect filter is like a "guard", blocking large particles; The medium-effect filter prevents the growth of mold spores and avoids the "musty smell of heating." Scene 2: The combination of junior high efficiency filters at the fresh air inlet of the central air conditioner is like "three lines of defense" : the initial effect of stopping sand and dust, the middle effect of filtering pollen, and the efficient capture of PM2.5 to ensure that the warm air blown out is clean as new. Scenario 3: Medium effect filter in radiator return duct to reduce dust accumulation and cleaning frequency (30% maintenance savings per year!) At the same time, the quiet design allows the heating to "work quietly".
Modular filter like Lego blocks can be detachable and replaced, magnetic initial effect filter "one pull is replaced", medium and efficient filter material can be combined and upgraded, suitable for different needs. Self-cleaning coating Medium effect filter material surface with nano TiO₂ coating, can decompose oil and dust, extend the service life to 12 months, eliminating the trouble of frequent replacement. Intelligent monitoring system filter built-in "blood pressure meter" (pressure difference sensor), real-time monitoring of blockage, when the resistance rises automatically adjust the wind speed, energy saving and efficient.
After installing a three-level filter in a shopping mall in Beijing, heating energy consumption decreased by 8.2%, PM2.5 almost disappeared, and maintenance costs were saved by 40%! Zhengzhou hospital ward high efficiency filter + ultraviolet sterilization, so that the concentration of bacteria from 500 to 10 (national standard requirements ≤500), patients breathe more safely.
Future trend: Filter more and more "understand you" new material PET composite filter material is coming: filter efficiency is increased by 30%, resistance is lower, heating is more energy saving! The intelligent linkage AI algorithm automatically adjusts the filter level: the haze day automatically opens the "strongest mode", and the good weather "energy saving mode" runs. Environmental protection recycling waste filter material can be recycled 60%, reduce pollution, warm people at the same time warm the earth. The high efficiency filter is not only the "protective shield" of the heating system, but also the "double engine" of health and energy saving. Next time you turn up the heat, remember to thank the air guards who are using technology to protect your every warm, clean breath.
