Makes little sense that one pays $15.00 for 10 little filtershere but $18.00 for one diffuser 400ESN261.

Yes, item 400HC228 comes with the diffuser so it is a much better deal!

exactly what I was looking for. I was receiving refills automatically from my insurance carrier. They did not send me replacements for this product. Mine was getting dirty, but they only told me to wash it. Washing it tore it up so it did not fit so well, so I returned to RESPSHOP to supply my wants. Thank-you for your kind assistance.
