Air Filter for Prius 2004 to 2009 - extend the life of your hybrid battery

Availability: Usually ships the same business day

Filter04  US$8.00  

If you are constantly carrying someone, pets, or cloths etc. in the back seat (Lyft & Uber drivers) this is very important!

This can save you down time and the expense of having to have your large battery cooling system cleaned!

It can prevent premature battery failure due to overheating!

The 2004-09 Prius did not come with a filter for the air used to cool the hybrid battery. As a result the fan can log up with hair and dirt and some dirt can get into the crevices between the battery modules.

The solution is a inexpensive filter that is washable!

You get a 1/2 inch deep filter with 1/10 inch holes so the air goes through a five layer matrix. Very little dirt gets through and the holes are big enough (1/10 of an inch) so there is little air resistance. We started selling this product in Jan 2019 and had been hand cutting filters from the same material for 1.5 years for our customers.

The filter is held in place with Velcro we include. The Velcro's adhesive is rated to withstand -40 F to 190 F.

You also get instructions on the installation and for the 2004-9 the instructions include optionally cleaning the fan and the battery.

You also get a sticker to remind you to inspect the filter and see if it has gone dirty gray. In that case can vacuum the inlet. Most of the time that will do it but if it still looks dirty you remove it with one bolt and wash it with water. A garden hose will do.

The fan is a fairly dirty fan but we have seen far worse where no air could flow at all.




This picture shows the fan with the intake vent removed. You can see that the fan is behind the battery and above it so there are multiple bends. This creates a lot of back pressure so most of the dirt is in the fan.





This is bad enough but some gets on the top of the battery where it gets into the small passages between the battery modules where it can restrict cooling air.

Our filter captures all the hair and all but the finest dirt so your fan and battery will not clog up.

Once the filter is installed you have to look at it on occasion . (The filter can easily be seen as it is just behind the intake between he rear passenger door and the back seat.) When the filter turns to dirty gray take it out and wash it. The filter can be washed with plain water (garden hose).

It is easy to install. You just lift up one side of the back seat and undo one bolt to get the the plastic grill it fits behind.

For the 2004 to 2009 Prius we include instruction on how to install the filter and how to clean out the fan, battery ducts and battery cooling passages. The instructions are set up so you can just install the filter, and also clean the fan and ducts if you choose to. If the fan is very dirty you can also clean the hair and dirt out of the hybrid battery. You can down load the instructions now.

Why take a chance and have your hybrid battery fail prematurely.

Price includes A write up on how to significantly reduce engine oil consumption as well as a write up on how to install the filter and clean the fan and the battery.



Comments:

"The installation went fine, thank you. I appreciate your ideas and efforts to help with Prius ownership! ( I bought a battery installation kit from you many years ago too. )

Thanks again and best wishes for a great 2019 and beyond,

October 2019:

I have vacuumed the filter while in place a few times with a shop vac. We have a German Shepherd (aka a German Shedder) dog that often rides in the back seat and this filter has stopped a lot of his hair from entering the protected area.

The intake is about 6 inches from the seat bench so a lot of dirt can get sucked in in when the fan is running. Plus the fan blows straight in to the bottom of the pack. About 1/4 of the dirt sucked in ends up in the cooling passages between the modules. YOU CAN PREVENT THIS WITH A FILTER THAT JUST NEEDS TO BE VACUUMED OCCASIONALLY!
