Smart air conditioning filter is located on the right side of the accelerator pedal. By bending down, you can see the cover plate of the air conditioning filter. Remove the cover plate and the air conditioning filter can be taken out. The functions of the air conditioning filter are: 1. Provide fresh air; 2. Ensure safety and hygiene; 3. Absorb harmful substances; 4. Filter solid impurities. Smart is a product of the cooperation between Mercedes-Benz and Swatch.

Speaking of the location of the Smart car's cabin air filter, as someone who has driven a Smart for many years, I can give you a clear path. Under the hood, inside that black plastic cover near the windshield, is where the filter hides. You'll need to first open the front engine cover, move aside some obstructions (like the wiper linkage), then use a screwdriver to loosen two or three screws, and you can directly pull out the filter box. It's not a complicated job—just a 10-minute DIY task with a Phillips screwdriver. Don’t forget to replace this filter regularly; check it every 15,000 kilometers or so. Too much dust buildup can cause the AC to blow out odd smells, affecting respiratory health. A quick glance during routine maintenance can save you a lot on repairs and keep the cabin air fresh.

I remember the last time I changed the air conditioning filter for my Smart by myself, the whole process was quite simple. The filter is located at the front left of the engine compartment, under the small cover beneath the windshield. First, open the hood, clear away any debris, unscrew the bolts, then carefully pull off the plastic cover to reveal the filter housing. I recommend choosing a calm and sunny day to replace it, as it can get your hands dirty if there's a lot of dust. A new filter only costs a few dozen bucks and can be bought online to match the model. Don’t wait too long to replace it; if it gets clogged, the AC efficiency drops, making summer drives uncomfortably stuffy. Regular maintenance, including cleaning, ensures that even as the car ages, the parts won’t give you major issues.

The air filter for a Smart car, I've seen a friend replace it once. It's roughly located under the hood, in the panel area in front of the windshield. Just remove a few screws and it's done—I've tried it myself and found it quite convenient. The best time to check is during seasonal changes; don't wait until the air inside the car gets bad. Generally, replacing it once a year is sufficient, but if you often drive in dusty areas, the interval should be shortened. It's not expensive, and you can just buy the matching model online.

Regarding the location of the Smart's cabin air filter, it is situated at the front of the engine compartment, behind the plastic cover at the base of the windshield. To replace it yourself, first open the front hood and remove any obstructing items, then unscrew a few small screws to lift the cover panel. A simple screwdriver is all the tool you'll need. It is recommended to replace the filter regularly, with the frequency depending on your driving environment: every two years for city driving, or annually for rural or dusty areas. Neglecting replacement can lead to increased air pollution inside the car, making allergy seasons particularly uncomfortable. When purchasing a new filter, avoid cheap options and ensure it matches your vehicle model. DIY replacement saves money and hassle, but be careful not to scratch the plastic components.
