Customizable and universal dimensions - cut out the 4.1 x 4.5 inch sheets to fit all shapes of litter boxes (square, round or self-cleaning). No adhesive required - simply place under the litter box or stick to the ventilation panels. Eco-friendly and pet materials - non-toxic and dye-free charcoal pads are safe for cats and your home and contain no chemical fragrances that irritate sensitive pets. Low maintenance air purification - replace every 20 days for optimal performance. Discard used leaves directly; no tedious rinsing or cleaning required. Suitable for clumping, crystallized or biodegradable litter. Multilayer odor protection - triple layer design (carbon core + polyester mesh) absorbs and neutralizes odors three times faster than a single-layer filter.
