Upsides of no oilfield in a 2000 TRX250

Ok, at a loss here. Changed oil on my recon, no paper filter to change. Honda usually does thing right, this seam like a not so right idea. How is no filter a good thing? Even my riding mower has a oil filter.

In repair manual see a oil screen in the engine that need cleaned, Can’t believe that gets cleaned very oftin as would have to split the engine. Is a Honda dealership oil change for my bike like $1200.00? Maybe more if they have to split the case, lets make that an even $2000.00. Crazy!
