This filter is compatible with: 【HP04・TP04・DP04・HP05・TP05】 By installing it in these models, you can achieve maximum purification performance. 【High-Density Materials】 In terms of the dual-layer material that protects your family's health, we use a high-density filter made by pleating HEPA micro-glass fiber over 200 times, and further combining it with "upgraded activated carbon." The pleated structure significantly expands the surface area of the filter, allowing it to capture even the smallest particles of dirt. This dual-layer structure effectively removes substances such as viruses, dust, and pollen floating in the air, creating an environment where people with allergies, babies, and the elderly can breathe clean air. 【360° Dust Collection Technology】 The dust collection function removes 99.97% of PM0.1 fine particles. It is equipped with a 360° ultra-fine glass fiber HEPA filter, capable of removing 99.97% of PM0.1 level (ultra-fine particles). Furthermore, it removes not only pollen but also mold spores that tend to breed in humid environments, bacteria that are commonly present indoors, and dust mite feces without fail. 360° omnidirectional dust collection circulates clean air throughout every corner of the room, purifying "invisible dirt." 【Powerful Deodorization】 The deodorization function maximizes the adsorption power of activated carbon, powerfully breaking down and removing various household odors. It can handle a wide range of odors that you might be concerned about in daily life, such as cooking odors (oil smell from frying, the smell of raw seafood) from the kitchen, pet odors associated with pet ownership, and the musty smell of indoor-dried laundry on rainy days. Even those who spend a long time at home can maintain a comfortable indoor environment. 【Recommended Replacement Guide】 The recommended replacement time for the filter is once a year, based on a typical household usage pattern of 12 hours a day. The replacement method is also easy, allowing even the elderly to perform maintenance with peace of mind.
