MO99 is simply the best refrigerant if you are considering replacing the refrigerant in your old home air conditioning system. It is ideal because it cools as well as R22 while costing significantly less. Freon™ MO99 refrigerant has proven to be a reliable and cost-effective, non-ozone depleting retrofit refrigerant. In many cases, systems converted to this refrigerant are operating with the same mineral oil or lubricant that was used with the previous refrigerant. Freon™ MO99 refrigerant has shown to provide similar system performance as when operating with the previous refrigerant. Using these retrofit guidelines, direct expansion (DX) residential and commercial air conditioning, and medium and low temperature refrigeration systems containing R-22 can be easily and economically converted to Freon™ MO99. This allows existing equipment to continue operating safely and effectively for the remainder of its useful life.

Retrofit Choice for R-22 Direct Expansion Systems in Residential and Commercial Air Conditioning, Direct Expansion Chillers, Medium- and Low-Temperature Refrigeration Freon™ MO99 is a non-ozone depleting HFC refrigerant designed to replace R-22 in existing DX residential and commercial AC and medium- and low-temperature refrigeration systems. Freon™ MO99 is compatible with traditional and new lubricants; in most cases, no change of lubricant type during retrofit is required. Oil return is determined by a number of operating and design conditions; in some complex systems, ester lubricant (POE) may need to be added. Minor equipment modifications (e.g., seal replacement) or expansion device adjustments may be required in some applications. Field experience has shown that Freon™ MO99 provides performance that meets customer requirements in most properly retrofitted systems. Freon™ MO99 provides similar cooling capacity and energy efficiency to R-22 in most systems, while operating at a lower compressor discharge

Best air flow
Size: 9.6" x 11.1" x 2.2"
I have a 2022 ram 1500 four-door. The factory filter from the ram dealer is about $40 but it’s not reusable. That was the only one I found that had good airflow into the cabin. I tried several other brands but the airflow was reduced excessively. The ram filter was 15 mph, most of the other aftermarkets dropped the airflow to about 9 mph. I just installed a K&N reusable filter and the airflow is back up to 15 mph. Great job K&N!!

Fits Well and Reusable. I'm Happy.

For less than the price of 2 disposable FRAM CV11671 cabin filters for my 2019 RAM 1500 and this will last forever. If it gets wet, like I've had happen with the paper throw-away filters due to stuff falling off trees in the spring and clogging cowl area water drains and backing up into filter ( yeah, that's a thing ) and can clean and dry this filter and reuse. Great directions came in the box along with a sticker to point out that this is a lifetime filter so someone doesn't throw it away. Do this yourself. Don't let some auto repair shop talk you into it. I was getting tires balanced recently and heard a quote they gave over the phone of $79 to do this. I don't know what kind of vehicle that was for but this ain't rocket science. Don't get ripped off. Now back to this filter. There is no arrow for air flow so I figure it flows well both ways and just put it in with the K and N logo right side up and facing out. It's not a straight in shot the way RAM positioned the opening for the cabin filter slot but was no big deal. Also realize this isn't a perfect square filter ...It's a rectangle so don't try to shove the fat end in and say it doesn't fit. I haven't noticed any air flow differences with the heating / ac system but some people say they do. I'm just happy I don't have to buy anymore disposable filters and can dry this if it gets wet. The cleaning and refresh spray kit is #99-6000 that comes with a 8oz and 12oz bottle and I'm trying to find that cheaper somewhere for when I do clean this thing.

Can’t go wrong with K&N
Size: 9.6" x 11.1" x 2.2"
So I recently took my pickup in to have some recall work done, half way through the process I got a call from the dealership stating I needed a new air filter and that a new one would cost nearly $60. I chuckled and told then to put the old one back in and I immediately came to Amazon and ordered this cabin filter. I’ve used K&N products in the past and have never been sorry, and that is the case with this lifetime filter. Upon installing this filter I noticed an IMMEDIATE difference in air flow into the cabin, it even smelled better. If this filter ever gets dirty Ira easy to clean and reinstall, paying for itself over time. Do yourself a favor and pick one of these up, you will not be sorry.

Fit my Subaru Forester perfectly!
This fit my 2024 Subaru Forester perfectly. The filters exhibited a high quality construction and was packaged well. Installation was easy and saved me a lot of $ vs. having my dealer install an OEM filter.
