Maintenance & Warranty
Exceptionally Long Service Life
Prihoda fabric ducts are not a short-term solution.
Diffusers made from good quality materials will last for 10 to 20 years or longer, depending on the choice of fabric and installation methods.
All Prihoda diffusers and ducts are made of high-quality, temperature- and shrink-resistant synthetic materials.
The particular fabric specified in your order is confirmed in shipping documents and printed on the label sewn into each piece.
Cleaning and maintenance of fabric ducts is easy. Ducts and diffusers made of permeable materials (Classic, Premium, and Recycled) can be washed normally in an industrial or commercial washing machine. Impermeable fabrics (Prihoda Light) can be machine washed on a gentle or delicate cycle. Specialty materials, such as Prihoda Plastic, Prihoda Glass, and Prihoda Foil, must be hand washed only. If the duct or diffuser has hold-open accessories, these solid elements can be removed easily before washing. Induction surface dirt on the outside of the duct or diffuser can be vacuumed off easily, so in many environments washing might not even be necessary.
See Materials for a full description of all Prihoda fabric options.
For proper maintenance, be sure to follow the washing instructions on the product label sewn into every section of a Prihoda fabric diffuser. For all fabrics, surface dirt can usually be removed with a vacuum cleaner directly on installed diffusers. desired, a disinfecting agent may be added with the detergent, although the customer is responsible to ensuring that the disinfectant chemicals do not affect the fabric. Re-install and allow to dry naturally. Prihoda fabric diffusers must never be dried in a drier.
For machine washable fabrics
Washable-fabric diffusers may also be uninstalled and laundered easily as needed. Heavily soiled materials should be dusted first, using a vacuum cleaner, compressed air, or a soft brush. Diffusers may be turned inside out for washing, if needed. Either regular or industrial grade detergent works fine. Wash at maximum temperature of 40°C (104°F), with a spin cycle set between 400-800 rpm, and rinse thoroughly. If
For non-machine washable fabrics
If vacuuming isn’t sufficient, clean the diffusers using a wet or dry sponge, soft rag, or brush, as needed. Heavily soiled diffusers may also be washed and rinsed by hand, using a mild detergent and a maximum of 40°C (104°F). Rinse thoroughly, and drip dry. Then re-install and allow to dry thoroughly once in place. Prihoda fabric diffusers must never be dried in a drier.
Any maintenance must strictly follow the washing label symbols sewn into every section.

The warranty is deemed to start on the day of sale (shipping date) and shall last for a period specified under “Warranty Period” below. For warranty to be valid all installation instructions must be strictly followed in addition to regular maintenance of the supply air units and filters. Supply air must be filtered to at least EU3 (MERV5), and the ducts must maintain original operating conditions in respect to design static pressure and air flow stated in the submittal or order confirmation. Any deviation from the original design intent that may have an adverse effect on the material or accessories may void the warranty. Furthermore, any deviation from Prihoda’s recommendations will void the warranty unless explicit written consent is given by an authorized representative directly employed by Prihoda.
The ducts shall be installed in strict accordance with Prihoda’s installation instructions and allowed to hang freely without touching the structure or surrounding environment. The warranty will be null and void if exposed to open flame, dripping liquids, harsh chemicals, temperatures above Prihoda’s recommendation, or sharp edges/objects. If installed in a natatorium or pool room, the pool must be properly balanced with normal amounts of chlorine/chloramines in the environment. Non-fabric articles and accessories are covered for a period of 12 months. Washing must be done in strict accordance with Prihoda’s maintenance instructions and must not exceed 50 washings.
The warranty does not cover consequential loss or damages, labor, shipping, rental equipment, tools required, natural disasters, war, or acts of God. The warranty may not be executed in the form of a cash payment; it is available only in the form of credit for repair or replacement, which is at the discretion of Prihoda. A claim must be executed by informing an authorized Prihoda representative at which time a full written claim and photo documentation is requested. If deemed necessary, a Prihoda representative will be allowed to visit the installation for inspection.
