The BabyComfyNose frees you from that - and it's FREE. Household facial tissue inserted into the body of the BabyComfyNose is actually a more absorbent and effective filter than foam rubber. Tissue pores are much smaller than those of foam rubber, and tissue is an inherently absorbent material, whereas plastic foam rubber is not. The result is that tissue is just a better filter.
BabyComfyNose is available two colors? Each child should have his or her own aspirator. Ideal for siblings and multiples.
