Car air conditioner: clean the filter to avoid bacteria


Can the air conditioner be turned on in 2020? This is the question that many ask themselves, given that Coronavirus spreads right in the air. Opinions are conflicting, but most scientific experts say that air conditioning systems should not be dangerous, provided that they are well cleaned and sanitized.
All air conditioners, including those for cars, must be thoroughly cleaned before being turned on. In the period when they are not in operation, thousands of bacteria and harmful particles nest in pipes and ducts and especially in filters. It is therefore necessary to clean the filter of the car air conditioner thoroughly before the season.

Why must the filter always be clean?

The importance of the air conditioning filter should not be underestimated. This is the way to protect yourself from bacteria and mites present in the external environment: let's not forget that the operation of the air conditioning requires the collection of external air and its introduction into the passenger compartment. Here are 3 reasons to clean the air conditioning filter:

1.       avoids the formation of bad smells in the passenger compartment;
2.       reduces the presence of harmful bacteria and micro-particles;
3.       increases driving comfort .

The health of the driver and his passengers is therefore paramount. But be careful: alongside correct filter cleaning, careful sanitization of the passenger compartment must be associated. And therefore dashboard, mats and seats : wherever mites and bacteria can be laid.

When to clean the filter

In the winter season it rarely happens to turn on the car's air conditioning. With rising temperatures, the overwhelming heat of the passenger compartment is a danger that can also come suddenly. Just leave the car in the sun for a few hours. The mistake to avoid is turning on the air conditioning without first cleaning the outlets and filter .
After being inactive for several months, the air conditioning system needs a vigorous makeover. We therefore recommend cleaning in the spring season, to be ready for the explosion of the great summer heat.

How to sanitize it?

Especially in this emergency period linked to the spread of Covid-19, the so-called New Coronavirus, hygiene is the best weapon we have to protect ourselves. Cleaning thoroughly and sanitizing environments and surfaces therefore becomes fundamental.
With the gradual recovery of economic activities, many people will resume moving by car. And rising temperatures will require turning on the air conditioning. How to sanitize the filter?
First of all, the instructions provided by the Used Cars for Sale in Philippines and manufacturer must be scrupulously followed . Each car is in fact a world of its own, and in the instruction booklet you will find:


  1. the location of the filter
  2. instructions to clean it
  3. how to eventually disassemble or replace it.

Generally, you just need to carefully vacuum up dust and bacteria and clean the filter with the appropriate detergents indicated. Do not forget to sanitize the vents from where the air comes out, an operation to be performed even in the winter months.


One last tip: after sanitizing, turn the air conditioning on at full power for at least 5 minutes , taking care to open the car windows. This will eliminate any dirt and detergent residues present in the pipes.

When to replace the filter?

The air conditioning filter should be replaced every 15000 km driven by the car. It is an indicative estimate and for timely information we advise you to check the instruction booklet of your car. If you frequently use the vehicle, you will need to replace the filter at least once a year .

Even if you perform a rigorous cleaning, the filter still has its own specific life cycle which runs out after a certain number of uses.

You may need a replacement even if the filter is malfunctioning: a typical alarm bell is the stench that forms in the passenger compartment every time you turn on the system. If even after a thorough cleaning the bad smell disappears, the time has come for the replacement, which however does not entail excessive costs.
