Oase BioMaster Prefilter Upgrade KitThe Biomaster upgrade kit can be retrofitted to any model Biomaster filter. Kits are available for all sizes, and can be used on both Thermo and non thermo versions of the filter. A newly designed tube inside the prefilter ensures flow rate is maintained for longer, thereby extending the period between cleans of the prefilter foams. Used in conjunction with the new 10ppi foams, this serves to provide adequate prefilter protection for the main filter

This is a super cute, and frankly, fairly high fashion little hoodie. The price was great for what it is. Really nice soft (terry?) inside. Double fabric hood. Really soft. It has an oversized cut which makes it easy to get on and off, but is just the right length to make the sizing look great and intentional - it doesn't look too big. I love the color. It's high quality, and I didn't notice any shrinkage. Even the hood is cut in a chic way. Not your average kids' hoodie.
