Dual-Density -
multi-section, long-life filter
A true dual-density filter. The first filter section is open, springy, and resilient with
high denier and low density. The second filter section contrasts by being thin, stiff,
rigid, and dense, with fine denier. Together, they make a high-depth-loading, long-life
filter perfect for automotive carbon canisters. This material is also excellent for vacuum
cleaners, furnace and air-conditioner filters, and pleated filters.
Filter Section 1:
- Open, springy, and resilient
- Coarse, high denier
- Low density
Filter Section 2:
- Thin, stiff, and rigid
- Fine denier
- High density
Filter Section 1 + Filter Section
2: the result of combining the two sections is phenomenal!
- Extremely long life.
- Will not distort and will die-cut straight.
- Exceptionally effective! example:
large particles "bounce off", and carbon is prevented from moving through the
multiple layers, in automotive carbon canisters. Two unique constructions provide a
"true" dual-density medium.
