Blue Pure 311i Max Particle + Carbon Filter

I’m glad I signed up for the service to mail new filters.

This makes it easy to remember to change the filter. The filters are a good price with free delivery. It’s Easy to change the filter. I was shocked at how dirty my old one was. I will vacuum the outside cover ‘sock’ more often. I would like to try the allergy one next spring, but it was sold out.

Great longevity and performance

Been using this type of filter for almost two years. It works great and has kept my allergies and asthma complications to a minimum. Highly recommend.

Easy to order

Order came promptly and was easy to install. Cleaning instructions of outside cover were helpful.
