Each unit is 8 feet long and has an outside dimension of 12.75 inches. Conduits and manifolds are manufactured using recycled polyethylene and feature snap-lock couplings and PVC piping for easy system assembly. With a compact design, delivery can be made using a standard pickup truck. 800-221-4436;

Filter Media

Eljen Geotextile Sand Filter

The GSF, or Geotextile Sand Filter system from Eljen, is designed to provide treatment and dispersal in the same footprint with easy installation and minimal maintenance. It is used for commercial and residential applications. Utilizing a two-stage pretreatment process, the geotextile modules apply filtered septic tank effluent to the soil, increasing the soil’s ability to accept effluent and increase the long-term acceptance rate. Its design provides increased surface area for biological treatment that greatly exceeds the module’s absorption area. Open-air channels within the module support aerobic bacterial growth on the module’s geotextile fabric interface, surpassing the surface area required for traditional absorption systems. The system is tested and certified by NSF to NSF/ANSI Standard 40. 800-444-1359;

Sim/Tech Filter pleated filter units

Pleated filter units from Sim/Tech Filter provide gravity effluent filtration in septic tanks and turbine pump filtration in pump tanks. The filtration size is 3/32-inch in two dimensions. Flow channels in the pleated material increase longevity. All filter types start at over 2,000 square inches of filtration area. The 45% open area (over 900 square inches) is equivalent to 800 linear feet of 3/32-inch slots. Various configurations and larger units are available. 888-999-3290;

Vent Pipe Filters

Pagoda Vent

Decorative Pagoda Vents come in 16-, 24- and 36-inch sizes. The original vents are bark (brown) or moss (green) color to blend into the landscape. The newest copper offering will add patina over time or can be maintained as a pristine copper landscape feature. All versions support the long life of system components by providing septic field microbes the oxygen they need to thrive, concrete tank gas release to mitigate microbial-induced corrosion, and pressure relief for pumps. An optional odor filter cartridge uses concentrated media for years of odor control, according to the maker. 888-864-1468;

Simple Solutions Distributing WVI Inline

The WVI Inline activated carbon filter from Simple Solutions Distributing is installed in an attic or crawl space inline with the current vent to remove septic odor. The filter comes in 4- and 6-inch sizes, with the smaller unit able to be bushed down to 1.5-, 2- and 3-inch sizes. It comes with 2 pounds of Sulfursorb Plus activated carbon, which is poured into the 2-inch fill port. The unit accepts an optional screw-in saturation indicator that changes color to indicate when carbon needs to be changed. It is suitable for extreme, cold climates, as it is enclosed in an attic or crawl space. It can be installed in any climate where septic or sewer vent odor exists and the roof vent filter needs to be hidden. 973-846-7817;

The Dirty Bird septic vent

The Dirty Bird provides an alternative to the standard septic vent required by many municipalities for new residential and commercial construction. It is an easy-to-install septic vent shaped like a birdbath. Meeting U.S. Environmental Protection Agency septic-venting regulations, it controls odors through a replaceable charcoal filter and vents gases through holes at the bottom of the pedestal so nothing enters the septic system. Fade-resistant (UV stabilized), lightweight and recyclable, it is available in granite, sandstone and terracotta colors. It is constructed of 100% low-density polyethylene and stainless hardware. It is 32 inches high with a basin width of 23 inches and footprint of 12 1/4 inches. 866-968-9668;
