When selecting a Home Altar, the material quality is the most critical factor affecting both price and longevity. For premium markets, prioritize solid hardwoods like Teak, Rosewood, or Sandalwood, which offer natural resistance to pests and warping. Ensure the surface finish uses non-toxic, heat-resistant lacquers to prevent damage from incense heat or oil lamps. For budget-conscious tiers, high-density fiberboard (HDF) with wood veneers provides an aesthetic look at a lower price point, but you must verify formaldehyde emission standards (E1 or E0 grade) for indoor safety.
