When was the last time you cleaned your air conditioner's filter?

Today, the admin received a private message from a friend asking why their air conditioner is so power-hungry, and it suddenly reminded me of this post. Seeing this, do you still dare to turn on your AC directly? 😱 The originally white air conditioner filter turned into this when removed! It's not just a day or two of dust, but a thick layer, to the point where you can barely see the filter's color... Think about it, when you come home every day and turn on the AC, has the air blown out been properly cleaned? Many people think that AC maintenance is only needed when it's not cooling, but they forget the most basic filter cleaning. When the filter is clogged with dust, it not only affects air circulation but can also reduce the AC's efficiency. Don't wait until the AC stops cooling or dust is flying everywhere to think about cleaning it! Take a few minutes today to remove and check your AC filter! Lastly, I have a question for everyone: When was the last time your home's AC filter was washed? A. Cleaned every two weeks regularly B. Washed once a month C. Washed when I remember D. I'm too scared to take it apart, afraid I'll see a similar sight 😂
