Cabin Air Filter

Electrostatic might work better and is probably washable--cheaper in the long run, and you're more likely to keep it clean that the paper filter.

 

Thanks for the link to the site. No non dealer parts shops here have the cabin air filter in stock, however they all say they can order them. Anyway, I noticed that the pollen type is by Bosch, which is a good manufacturer, however the electrostatic type is by Dens, which is a subsidiary of Toyota, so that would basically be a Toyota replacement part, but possibly better than the original.

I also show the actual price through your link above $26.81. That isn't too bad for a filter that will last about 12,000 miles.

It doesn't say if it is washable.

 

If your new filter has greater flow restriction than the original it will cause performance problems. At some point the added restriction can cause the coil to freeze up causing excessive head pressure and premature compressor failure.

This is the case with residential compressed refrigerant cooling systems. If automotive systems are markedly different, feel free to correct me.

 

Ray:

You mean like those 3M "Filtrete Ultra Allergen" filters marketed in popular HVAC sizes?

I believe they work as advertised, but I would *never* use a filter like that unless it was put in the same cabinet as an industrial HVAC with a DP monitoring system. Once the DP exceeds the preset limit, you get an alarm to replace the filter.

I like electronic air cleaners for residential HVAC use, with a HEPA bypass filter if you're sensitive to pollen or fine dust. The EAC cells really don't cause airflow problems, and they are easy to clean too.

For automotive applications with a replaceable filter, inspect frequently and replace when dirty.

Jay, I use the 3M filters in my house and set the thermostat to show "filter" every 30 days so I can keep an eye on how dirty it gets. Having 3 dogs/7 cats you wouldn't want it to get plugged up, :lol:

As for the Prius cabin filter, I have seen some really plugged up ones especially if trees are around. One was so plugged it restricted the air flow! It is so easy to check,maybe Toyota should put a light on the dash to let you know to check it like the "maintenance" light? The saying " Out of sight,out of mind" works here :roll:

That's what I like about the Bryant Evolution home control at my hobby farm. I can program when I get reminders about the filters and cleaning the EAC cells.

I suppose you have a Petting Zoo with all those critters. Don't be surprised if the return air trunk is full of animal fur, and make sure to check the A/C evaporator too.

I really like Electronic Air Cleaners. The stainless steel mesh prefilter is very easy to clean, and on most EAC's once the cells get too loaded up the indicator light goes out and you know it's time to soak them in dishwasher detergent.

I suggest all Prius drivers consider the following: At your favorite hardware store, buy a washable electrostatic filter sold for residential HVAC. Tpically you will see a 20 X 25 inch for $20. Cut the element into 8 3/8 inch or 21 cm squares. Keep a couple for yourself and the rest for Prius party favors, etc. Remove, wash and reuse.

To the Toyota employees who contribute so much here, I hope that not everybody takes my advice, and that your company can maintain a profitable service/maintenence operation. But frankly the Toyota part is not cost effective in this application.

 

My local Toyota dealership told me that the cabin air filter that comes w/ my '05 Prius is already the HEPA / Electrostatic type.

There is this new Photocatalytic air filter that we plan to import from Japan. They make one model for the Prius. It doesn't just trap. It supposedly breaks down the trapped allergens/pathogens as well with the use of an UV lamp or natural sunlight. So I assume it's reusable after washing & exposing under the sun?

A lil' preview:

No harm in trying to find something more cost effective,as long as quality doesn't suffer. I know all about the price differences since I own a Toyota MR2 and my wife has a Chevrolet Tahoe. Having worked at a Cad/Olds dealer in the 80's, I have first hand experience in the big price differences between domestic verses import.

 

Yuck, sounds like the intake filter on the HRV at my place. Now imagine if you always have to breathe air *that* dirty!

 

My 2008 and 2003 both have the original PolyFiber Cabin filter. Compressed air is nice if you have it, I have it but for this PolyFiber filter I prefer the kitchen sink and a little spray soap.

I have used dilute dish soap in a spray bottle and I have used Windex, both are fine then just rinse with water and shake dry... almost Zero dollars. Quick, easy and cheap.
