To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Read all the good reviews but from experience after buying the item, it is absolutely useless. I love the efficiency of the machine, but it always gives off a 'dusty smell' which I mistakenly assumed would go having fitted a new filter. I don't have any animals in the house, so the filter is not under extreme pressure. The unit appears to be a genuine Miele one, and well made - just ineffective.
It seems to be a common complaint , I have ordered this filter twice & have received the older light blue version without the timestrip on both occasions , I have returned them both , please supply what you are showing,, very misleading .
