# Healthy Home 101: Air, Water & Materials | Kingdom Builders > A practical guide to air, water, materials, moisture, lighting, and structure, with questions to help you plan your custom home with Kingdom Builders. Canonical page: https://kingdombuilderslmsw.com/learn Six parts of a home worth understanding before you build. ## 01. The Air You Breathe Fresh air, thoughtful materials, and filtration work together. Reducing pollutant sources, bringing in outdoor air, and using suitable filtration can improve indoor air quality. No single filter removes every pollutant. **Questions to ask** - Code compliance is the starting point for a ventilation design, not a promise of pollutant-free air. - Ask how outdoor air, kitchen and bathroom exhaust, filtration, and humidity control will work together. **Our building approach** - Wool insulation and material selection considered alongside the ventilation design. - Whole-home air purification, central dehumidification, and planned air circulation. - An energy recovery ventilator (ERV) to exchange indoor and outdoor air while recovering energy. - Filter selection and replacement schedules matched to the installed equipment. **Sources** - [EPA: improving indoor air quality](https://www.epa.gov/indoor-air-quality-iaq/improving-indoor-air-quality) ## 02. The Water You Drink & Bathe In Start with your water source. Choose treatment for what is actually in it. A water report or test helps identify what, if anything, needs treatment. Filter capabilities vary: check the specific model’s certification and look for independent third-party testing. **Questions to ask** - A plumbing specification and a water-treatment plan answer different questions. - The right treatment depends on the water supply and the substances a system is certified to reduce. **Our building approach** - Whole-house filtration with a dedicated fluoride filter, as described in our building approach. - A remineralizing 10-stage reverse osmosis system for drinking water. - Copper drinking-water lines from the reverse osmosis system to the tap. - Treatment choices reviewed against water results, product performance, and replacement schedules. **Sources** - [CDC: choosing home water filters](https://www.cdc.gov/drinking-water/prevention/about-choosing-home-water-filters.html) ## 03. What Your House Is Made Of Look beyond the surface. Ask what goes into each material and finish. Some building products release indoor air pollutants. Product selection, application, curing, and ventilation all matter; a natural-material label alone does not establish safety. **Questions to ask** - Code compliance does not tell you how an individual will respond to a particular finish. - Ask for product data and application guidance for paints, adhesives, cabinetry, and flooring. **Our building approach** - Solid wood trim and doors, with solid wood cabinetry. - Finishes that are not just low VOC, they are ZERO VOC and have ingredient transparency. - Finishes that are safe and natural: solid hardwoods, wool carpet, mineral paint, and natural stone are just a few of the many materials we specify to protect your indoor air quality. **Sources** - [EPA: controlling indoor pollutant sources](https://www.epa.gov/indoor-air-quality-iaq/improving-indoor-air-quality) ## 04. Moisture, Mold & Building Science Managing moisture starts with the details you cannot see. Moisture control is incredibly region specific and central to preventing indoor mold growth. Drainage, drying, ventilation, and vapor management need to work together. **Questions to ask** - A completed inspection is one step; moisture management continues through construction and occupancy. - Ask how window drainage, wall drying, crawl-space conditions, and indoor humidity will be managed. **Our building approach** - Documenting lumber moisture before closing walls, with a target below 12%. - Wool insulation in the wall cavities that is hygroscopic, meaning it ensures moisture content is below the threshold where mold can grow. - Pitched window sills, continuous weather barriers, unparalleled air/moisture sealing, rain screens, and many more. - Encapsulated, conditioned crawl spaces with an air and moisture barrier between the crawl and your home. - HVAC load calculations, central dehumidification, and bathroom moisture management. - Vapor-permeable paint to ensure water vapor can't get trapped in your walls. Our walls dry inward. **Sources** - [EPA: moisture and mold control](https://www.epa.gov/mold/what-are-ten-things-i-need-know-about-mold) ## 05. Light, Wiring & Everyday Comfort Lighting can deeply affect your sleep. Circadian lighting is God’s natural way to gain deeper, more meaningful sleep. **Questions to ask** - Electrical safety requirements and personal lighting preferences are different design considerations. - Discuss room use, dimming, glare, and connectivity needs before the wiring plan is finalized. **Our building approach** - Panel and meter locations planned with the electrical design and utility requirements. - Hardwired internet connections and a Wi-Fi kill switch conveniently located in the master bedroom. - Dim-to-warm circadian lighting meant to improve your quality of sleep. - Lighting selected with attention to dimming compatibility and flicker performance. - Whole-home surge protection included in the electrical plan. **Sources** - [WHO: electromagnetic fields and health evidence](https://www.who.int/news-room/questions-and-answers/item/radiation-electromagnetic-fields) ## 06. Structure You Can Feel A well-built home should feel solid underfoot. Floor comfort depends on spans, loads, connections, and the complete floor assembly. Design criteria should be established up front. Simply designing to code minimum deflection ratings and loading is not enough. **Questions to ask** - Code minimum standard is a baseline; the structural design is specific to the home. - Ask the designer how floor deflection, vibration, and connection details are addressed. **Our building approach** - Floor stiffness targets established with the structural designer. - Live and dead loads should be specified. - Subfloor should be glued and screwed down. Nails can back out over time. - Flooring should be fully glued and nailed down. The glue should have a vapor barrier to prevent movement in the wood. --- Where Health Meets Construction.
