This is a great Sealand Sanigard Vent Filter. It lasts quite a while. It does a great job. I couldn't imagine not using one! They are an essential part!
I'm glad that I found this filter at nearly $40 off! It was simple to install. A Sealand Sanigard Vent Filter is essential to keep your boat smelling great. This one works perfectly
Replacement cartridges for Sealand Sanigard Vent filters are long lasting. They are very easy to install. Plus they last for an entire season.
