Are there Air Purifiers with reusable filters?
I have owned the honeywell brand air filter and it was decent at cleaning the dust out of the air. Has anyone used an air purifier with reusable, cleanable/washable filters? If so which one(s)? I am looking for an air purifier that effectively removes/reduces the spring time pollen and dust from the air in my living space.
The only other way I have found is Obsessive Compulsive dusting and vacuum rituals by the hour. My kitty really hates the twice daily vacuum routine.

I am not aware of any ‘reusable’ filters that are effective for removing pollen. Most of the better air filters have a course, reusable pre-filter to extend the life of the real filter. The best filters usually have 3 or 4 stages of filtration, each one progressively finer so the HEPA core filter only has to be replaced once a year of less.
Generally, you don’t want to keep reusing a filter because the pores clog with allergens. In order to effectively capture the allergens, the pores have to be small enough and ‘washing’ a filter alters who the fibers lay down. As a result, their efficiency changes with each wash/dry cycle.
I’ve tried a lot of vacuums, and to be honest the best performing one I found was a little 7.2 amp Hoover with ‘allergen filtration’ bags. You pull so much dirt up over the course of a month, that HEPA filters clog quickly and reduce air flow through the vacuum. When my vacuum no longer feels like it is lifting up the carpet, then I replace the bag (usually about 75% full). One thing I have learned, the price has nothing to do with actual performance. I have settled on Hoover because I found that they really suck.

Remember, many of the cleaners used in the home are irritants. So by cleaning so much trying to help your allergies, you can unintentionally make them worse.
There are electrostatic air purifiers that do not even have a filter like the others. You take them apart and wash them. The Oreck 2000 is an example. You do not ever buy filters for it.
NOOOoooooo!!!!!
If you can wash it, it is not a very good filter. The most important thing in picking an air filter is to get the proper size filter for the volume of air you are going to clean. Most manufacturers rate their machines on square footage, but you are cleaning not two dimensions but three. You are not cleaning the surface area of the floor (square footage) but the volume of air in the room (cubic feet). First, determine the volume of the room (square footage times height of ceiling). Next, look at the amount of air the filter’s motor will move on each of the speeds (as expressed in cfm – cubic feet per minute).
Divide the volume of air in the room by the cfm of the motor and that tells you how many minutes it will take to get one air exchange. Divide 60 (the number of minutes in an hour) by the number of minutes for one air exchange. You want a minimum of 6 air exchanges per hour and more like 8 or 10 to really do the trick. Also, remember that ionizers don’t get rid of anything, they just cause particles to fall or stick together and stay away from anything that produces ozone.
Personally, I have austin air machines in my house because the filters last for years and years.
I’ll give you some links to read about how to pick a filter and a link to a site that doesn’t sell filters, it just rates them and finally a link to a picture of the machine I have. With the right size machine, you should not have to vacuum twice a day
