Yes we replace the cheapies once a month in the apartment building.if the tenant has asthma or allergies and needs the better filters then they have to buy them.The thicker filters are fine but have to be replaced more frequently than recommended.I have highest rating in my home for filtrete filters.Recommended says every 3 months but I change every 6 to 8 weeks otherwise it starts drawing to much power and cutting air flow from catching all the particles.

I found a local cabinet builder that builds cabinets for less than any big box store, but he doesn't use any particle board, only plywood for the backs and sides.

With used mobile homes, usually the flooring needs to be replaced and some subfloor repair work done (i.e. cut out old floor with soft spots usually particle board and replacing with plywood). 

I would stay away from the particle board cabs from the big boxes and find all wood RTA's. 

All plywood carcasses, not particle board like Ikea, and all soft close, all dovetailed drawers.

He said once you spray it on the floor to put kitty little on top and walk all over it crushing the kitty litter into finer particles.

The particle board crap they sell today is one and done composite board where if any water hits it then it goes 5 times it's size.

The thing is that everything in the area is 300 sq ft smaller becaus this house has an addition of an extra bedroom bathroom and dining room.all of the ones i found within 2 miles  in the last 6 months hadno updates, linoleum, particle board counters. old bathrooms and they were comping out at about 174 to @1050 sq ft up to 189 @ 1120. the home i have has an addition but it was done with brick to match the original home and it was done well so the house is about 1400 sqft. so i feel like a 187 valuation is a very conservative.

Stay away from Ikea, there's simply no reason to buy particle board cabs when there's great alternative at least as cheap.

The cabinets are hideous old walnut colored particle board and the corners are chipping.
