How often should I replace the Dyson V12 Detect Slim Absolute hepa filter?

Can I just wash the V12 Detect Slim Absolute hepa filter instead of replacing it?

Replace it when it won't rinse back to clean, the foam crumbles, or the pleats/mesh are damaged; a washable filter still wears out eventually.
Do I have to buy the genuine Dyson part, or will a compatible one work?
Yes — a compatible (aftermarket) hepa filter works well in the Dyson V12 Detect Slim Absolute as long as it's made for this exact model. Aftermarket options can save up to 60% versus the genuine Dyson part. Look for 4.3+ stars with plenty of reviews, and confirm the listing names your exact model.

Compatible hepa filter options for the Dyson V12 Detect Slim Absolute start around $13.99, with the genuine Dyson part around $34.95. The prices in the table above are checked against Amazon regularly; multipacks usually cost less per unit.
