We bought 2 Blue I5 Stic vacuums from INSE - both work very well but this filter is terrible - no HEPA and very poorly made, it's difficult to clean properly and needs to be cleaned every time we use it use the vacuum cleaner, which inevitably causes it to fall apart quickly - the manufacturer recommends changing the filter completely every 2-3 months, which means that if you use your vacuum cleaner every day, you're paying 6 x $10.65 per year for the filters , which makes the filters more expensive than the whole stick vacuum cleaner - at that price you can just buy a new stick vacuum cleaner every year - unprofitable and makes us unhappy with this situation - we can eventually return both vacuum cleaners and look for another one with better filters and less expensive spare parts
