1. Poor absorption & liquid reflow
Low-grade underpads use inferior pulp and low-absorption SAP. They absorb liquid slowly and fail to lock moisture firmly. After slight body movement or pressure, liquid easily flows back, leaving the surface wet and sticky.
2. Clumping, splitting & deformed core
Without stable composite fixation technology, cheap inner cores easily break, shift, clump, and layer after absorbing water. The uneven surface creates hidden water accumulation areas, leading to leakage, dirt buildup, and bacterial growth during use.
3. Unqualified raw materials & bacterial risks
Many low-cost pads use recycled materials and non-sterile raw materials. They often exceed standard bacteria levels, carrying hidden dangers such as E. coli and staphylococcus.
4. Harmful chemical residues
To cover yellowish color and bad odor, inferior manufacturers add excessive fluorescent agents, industrial bleach, and low-grade glue.
Final Thought: Safety Is More Important Than Low Price
A qualified underpad is defined byfast absorption, firm locking, breathable structure, safe materials, and zero irritation.
Never compromise on quality for a lower cost. True value lies in reliable protection, cleaner use experience, and long-term safety for every user and pet.
