Easiest to install so far
Style: HEPA
So the 2018 Honda Odyssey apparently checks the air flow and after a certain point it determines the cabin air flow is less than desirable. At least this this is what I’ve gathered after talking to my dealer. Buying a thick filter may not be better. This was the easiest filter to install. I didn’t have to gingerly coax it In without collapsing the filter. It fit easily and I didn’t have to cut it. Pro Tip: Write the date of install in case your dealership says “well cabin air flow is blah blah blah.” Just tell them to check the date. You should get 6-12months on a filter. My dealership wanted to charge a ridiculous amount for what is literally a 2 minute job. Decent filters will cost around $20. Thicker isn’t better. It all depends on how much crap you have in your glove box. And how much crap is in your air. It might take longer to get all the receipts, first aid kits, tick prevention kits, headlights for the Scouts that forgets theirs, oh that there’s that Leatherman and Mylar blanket is… The job entails emptying the glove box, who’s keeps gloves in these? Press the tabs to drop the box and then Voila there is the filter. It’s really that easy. Ok pull the cover off and pull the old filter. Unless you live in a really dusty environment or have squirrels that are destined to ruin your life there shouldn’t be any real mess . Pull it out and put this in. There’s air flow arrows but even if you did it backwards the van isn’t going to explode in a ball of flame, fueled by the forgotten Cheerios under the seat. Relax, you did it. The world still turns and you’re good to go. Now it’s time to think about the engine air filter. You can do it. It’s easy but the clips can be a pain so it’s better to grab an adult beverage before, just in case.

Great Product

This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

Works as intended but lowers airflow
Style: HEPA
I got this because of the wildfire smoke in my area. It definitely filters out smell compared to a regular filter so I'm assuming it's also filtering out larger particles in the air. However, I've noticed that the airflow is reduced by a lot and the car is a lot warmer on the same setting I've used for years. It's a trade off and I might just rotate filters depending on AQI and how hot it is since it takes like a minute to change it out. I would recommend it if you live in an area that's smoky or cooler but not in places that get hot.

Fits and filters great
Style: PUREFLOW
Perfect fit and replacement for my wife's car air filter. The air seems to be a little fresher after putting this one in i believe it makes a difference to spend a little more on a quality filter.

Fits 2018 Honda Cr-V LX
Style: Particulate Media
Fits 2018 Honda Cr-V LX FWD. Be sure to install this filter with the arrow pointing down. Note that the plastic cover that holds the filter in place has an arrow pointing up to show you which direction to orient the plastic cover, not the filter, which again, should have the arrow pointing down.
