The replacement item seems to be of great value as compare to a Genuine-kind filter. It only costs half of the price of the latter . The material used is of a good quality. The package came with prefilters ( carbon sponge screen ) .This spare screen arrangement has definitely made up to the standard if not as comparable to the original HEPA ; it comes to a very close level/rating. It is therefore the item is worth the money for its value.
