Carbon dioxide is not the only element you should be afraid of inhaling especially if you are in a place where old jeepneys, AUVs such as Tamarraw FX, Revo, Adventure, Crosswind & etc..., buses and commercial van like L300 and trucks that are running in your area you might not see it with your naked eye but it will adversely affect your health.
Also if what you say is true, then why do cabin filters get this dirty? Can you explain your point further? If basically only recirculated air in the cabin is so clean?
If you are putting a generic China made filter then you are risking your health to particulate matter that is unseen to the eye.
Allergens are not the main point of negative effects when using a cabin filter, that is where you are wrong. That is only an add-on feature from the cabin filter.
The main point of the cabin filter is to clear toxic pollutants from the atmosphere since your
immune system does not develop anti-bodies versus toxic pollutants.
I think you need to get re-educated on how an aircon
cabin(inside of a vehicle) filter works.
Doesn't mean that you are using the re-circulation that polluted air doesn't go inside the vehicle's interior/cabin I think you have a wrong idea or view on how the cars' air-con system works.
I'm here to tell you that you need to study and research how the AC system works in a vehicle. Polluted air enters through the ventilation system or the air-conditioning system.
Also generic China cabin filters has less fibers inside compared to high quality filters like Mann+Hummel & WIX brands, means less dust and pollutants are being trapped by the cabin filters since it is less dense and thinner than high quality filters.
Also FYI(For your information)
WIX Standard O.E. cabin filters only costs around
P380 for vehicles like Vios, Innova, Hilux, Fortuner & etc... up to Subaru models roughly around
P900.
JS Asakashi Standard filters only costs around
P300 for vehicles like Vios, Innova, Hilux, Fortuner & etc... up to Subaru models roughly around
P600
You might be buying China filters for similar or more than that amount because auto shops that sell generic China tend to mark-up their dirt cheap products to around
350 pesos to
850 pesos because they are unscrupulous types of merchants.
The usual tagaan and low quality tindahan/ retail shops are unlike the carefully chosen WIX or JS Asakashi authorized dealers which tend to be more on providing quality service, continuous long term business(Loyal clients) and tend to follow SRP(Suggested retail prices) formulated by reputable suppliers that handle well known brands.
According to the shops that are authorized dealers of either WIX or JS Asakashi is that they were chosen because they would agree and conform to the distributor's policies like
"NO ONE TIME BIG TIME SALE" type of selling, unlike those engage in selling low value and low quality imbento brands exactly like Circuit brand or similar with CD-R King type of brandings.
Again I'm not here to criticize or provoke people with their hearsay's beliefs, I'm here to educate people who loves cars and normal car owners here more on proper, actual, accurate & well documented facts and figures.
