Summer of 2026 is approaching: why is now the critical period for replacing car air conditioning filters?

With the rapid rise of temperatures in the northern hemisphere, high temperatures and humid weather in summer are approaching, and car air conditioning systems are about to enter the highest load operation stage of the year. Have you noticed that after turning on the air conditioning, there is a strange odor, the air flow decreases, and even discomfort such as dizziness and sneezing for the driver and passengers? There is a high probability that your air conditioning filter is severely contaminated and urgently needs to be replaced.

The cabin air filter is the only barrier to the air inside the car, like the "mask" of a car, responsible for filtering the air entering the cabin, blocking dust, pollen PM2.5, Fungi, bacteria, exhaust odors and other pollutants.

• The filter is filled with dust, leaves, and insect eggs, which can breed mold and bacteria. When the air conditioner is turned on, it has a pungent odor;
• Filter failure, PM2.5, Allergens entering the car directly can cause allergies, respiratory discomfort, dizziness, and nausea;
• Blocked air ducts, reduced air conditioning output, slower cooling, increased fuel consumption, and increased blower load;
• In humid environments, mold can multiply in large numbers, and in severe cases, it can lead to "air pollution inside the car", endangering the health of drivers and passengers.

1. Summer maintenance peak season (April ——June)
   As temperatures rise, the frequency of air conditioning usage has surged, leading to a global trend of car owners replacing filters. Demand is particularly strong in Europe, America, the Middle East, and Southern Europe. Data shows that sales of air conditioning filters increased by over 40% month on month in April, and May and June are expected to reach their peak for the whole year.
2. Awakening of Health Cabin Awareness
   In the post pandemic era, consumers have significantly increased their demand for in car air quality (IAQ), with high-efficiency filtration (PM2.5 ≥ 95%), antibacterial and anti mold properties, and odor removal becoming essential. The market penetration rate of the fourth generation full efficiency air conditioning filter element (physical+chemical+biological composite filter material) is rapidly increasing.
3. Policy and standard upgrade
   The European Union and North America have successively introduced new regulations on air purification in vehicles. Starting from 2026, new cars will be equipped with high-efficiency air conditioning filters as standard, and the demand for upgrading existing vehicles will be released. At the same time, the new policy of opening up three electric maintenance has driven the demand for independent repair shops to purchase high-quality filter cartridges.

1. Matching vehicle model: Select the specialized size for the car according to the frame number/model year.
2. Check the filtering level
   Ordinary: intercepting dust and pollen;
   Activated carbon: removes odors and adsorbs exhaust gases;
   HEPA high efficiency: filters out fine dust and allergens.
3. Material identification and workmanship: dense without stealing work, tightly sealed edges, and not easily shedding hair.
4. Vehicle environment selection: Choose activated carbon for urban commuting and high-efficiency for dusty roads.

1. Suggested replacement cycle:
   Conventional environment: Every 12 months/15000 kilometers;
   Areas with high dust/pollen/pollution: every 6 months/7500 kilometers;
   Mandatory replacement before the arrival of summer (April May).
2. DIY replacement steps (no tools required):
   Turn off the vehicle power and locate the air conditioning filter cover behind the passenger glove box;
   Open the cover plate and remove the old filter element (pay attention to the installation direction);
   Clean the dust in the air duct and install a new filter element (arrow pointing in the direction of airflow);
   Cover the lid and complete the replacement, the entire process takes ≤ 15 minutes.
