You could cover the gap with a strip of tape if you wanted edit it s also the wrong way round.
Air filter not sealed.
The merv rating also indicates the percentage of particles the filter will remove from the air passing through it.
Then remove the filter and dispose of it in a sealed bag.
I found my airbox like that countless times in my wrx.
Sealed buildings that are using old filters allow poor quality air to recirculate indoors.
In general a merv rating of 6 indicates that the filter will capture up to half of the particles in the air.
Wet is better as it tend to keep dust out of the air.
It won t make much of a difference so yes it s ok.
When there is suction the filter will be pulled against the box if anything so it really shouldnt be a problem.
If the filter is not sealed in the filter frame off the filter rack improper gaskets damaged filters etc air can easily pass through without have to go through the filter.
I noticed that my car did not have excelleration like it did before but i want to hear from people who know about this.
The blower fan creates a negative pressure and pulls the filter flush against the air handler.
The way the box is setup the filter is basicly self sealing.
If your air purifier has a fabric prefilter.
It was placed in a form that only 60 to70 of air must have passed through.
Is there more that happens to the.
The gaps created by improper installation and or poor gasketing may seem insignificant but they can have a huge effect of your filter s efficiency.
We inhale these particles and depending on your sensitivity they can cause minor problems like watery eyes coughing sneezing or trigger asthma related symptoms and other long term respiratory complications.
The gap is going to pull air in from the room but even still it s still passing through the filter.
And a rating of 11 or higher means that the air passing through the filter is.
So my question is what happens to a car in this situation.
A filter with a rating of 8 will trap 70 to 85 percent of air born particles it encounters.
These come in spray cans and are available at any hardware store.
