Review on 🔍 HQRP 2-Pack Washable Filter: Compatible with Eureka Optima 431, 437, Lightweight Vacuums – High-Quality Replacement by Andrew Smith

It took almost a week to arrive, said to be shipped via DHL but the address label says USPS. Postponed one more day due to delivery issues. The canister does not want to clog completely now. There are no instructions on how to clean the filter. I think it's better than buying a new vacuum cleaner to improve the suction power. It seems that the shipping costs were almost the same as for two filters.
