This automotive maintenance "how-to" guide was specifically written to assist owners of the 5th generation 2011, 2012 & 2013, 2014, 2015 & 2016 Hyundai Elantra (also known as the Avante or i35) in cleaning or replacing the HVAC system's cabin air filter element.

Owners of other Hyundai or Kia vehicles such as the Accent, Sonata, Azera, Veloster, Tucson, Santa Fe, Veracruz, Genesis, Forte, Optima, Rio, Soul, Sorento, Sportage, i10, i20, i30, i40, Tiburon and Sedona may also find these DIY instructions to be helpful.

A few of the compatible A/C cabin air filter include the following with their part numbers: Fram CF10728, ATP CF-173, Purolator C35660, Wix 49377, Beck Arnley 042-2093, Bosch P3745, TYC 800189P, K&N VF2037, Ecogard XC35660, ACDelco CF3241 and Hastings AFC1367.

No tools are needed to access the cabin air filter. A wet/dry shop vacuum is useful if you decide to clean the existing filter.

Pull Out Side Stopper
The first few steps are to get into the front passenger seat of the vehicle, open the glove box door and empty out the contents.

Then locate the glove box damper arm on the right side of the glove box and gently pop it off the mounting peg.

The glove box is also held up by two circular plastic stoppers with one on each side wall of the glove box.

Slightly raise the glove box before rotating the side stopper pegs 1/4 turn counter clockwise and then pull them straight out.

Carefully lower the glove box down towards the floor mat.

Cleaning With Vacuum

If your old cabin air filter is relatively clean like the one pictured above, you can just tap out the large debris and clean out the dust with a wet/dry shop vacuum before replacing it.

If your old filter is dark grey or black and clogged with dirt, dust, hair, leaves, insects and other debris, you should replace it with a new filter element.

I recommend buying the Fram CF10728 "Fresh Breeze" cabin air filter since it has excellent reviews on Amazon.
