Your HVAC system’s performance starts with the air filter.

Day and Night HVAC systems are designed for energy efficiency and reliable airflow, but they rely heavily on proper filtration to deliver clean, conditioned air. At Filterbuy.com, we've seen firsthand how skipping regular replacements or using incompatible filters leads to premature wear, rising energy costs, and indoor air that feels anything but fresh.
We recommend replacing your 16x25x6 filter every 3–6 months, depending on usage and local air quality. Many Coral Springs homeowners who use Filterbuy filters report noticeable improvements in dust reduction and fewer allergy flare-ups, especially during peak heating and cooling seasons.

Indoor Air Can Be Dirtier Than You Think
According to the U.S. Environmental Protection Agency (EPA), indoor air can be 2 to 5 times more polluted than outdoor air, and sometimes even 100 times worse under certain conditions.

Dirty Filters Can Spike Your Energy Bills

Frequently Asked Questions
What does 16x25x6 mean on an HVAC filter?
These numbers refer to the filter’s dimensions in inches: 16 inches wide, 25 inches long, and 6 inches deep. It’s essential to match this size exactly to ensure a proper seal and effective filtration in Day and Night HVAC systems.
How often should I replace my 16x25x6 Day and Night filter?
We recommend replacing your filter every 3 to 6 months, depending on factors like local air quality, whether you have pets or allergies, and how often you use your HVAC system. Regular replacement helps maintain cleaner air and improves overall system efficiency.
What MERV rating is best for my Day and Night HVAC system?
For most homes, MERV 11 provides the best balance of airflow and filtration. However, if you have allergies, pets, or live in a high-dust area, MERV 13 offers higher filtration performance. Filterbuy offers both MERV 11 and MERV 13 options in the 16x25x6 size.
Can the wrong filter size damage my HVAC system?
Yes, using an undersized or ill-fitting filter can allow unfiltered air to bypass the filter, leading to dust buildup in the ducts, reduced system efficiency, and even premature wear or breakdowns. Always use the correct filter size, such as the 16x25x6 for Day and Night units.
