Poly Wire vs Pleated Filters. Which is best for my HVAC system?

Poly wire filters and pleated filters are two common types of air filters used in HVAC systems, including water source heat pumps. Here are the pros and cons of each type:

Poly Wire filters

Pros:

• Low cost: Poly wire filters are generally less expensive than pleated filters.
• Low resistance: Poly wire filters have a low resistance to airflow, which means that they don't put a strain on the HVAC system.

Cons:

• Lower filtration efficiency: Poly wire filters typically have a lower MERV rating (a measure of filtration efficiency) than pleated filters, which means that they may not capture smaller particles.

Pleated filters

Pros:

• Higher filtration efficiency: Pleated filters typically have a higher MERV rating than poly wire filters, which means that they can capture smaller particles and provide better indoor air quality.

Cons:

• Higher cost: Pleated filters are generally more expensive than poly wire filters.
• Higher resistance: Pleated filters have a higher resistance to air flow than poly wire filters, which means that they can put more strain on the HVAC system.

Overall, the choice between poly wire filters and pleated filters for an HVAC system in a condo will depend on the individual's priorities for cost, filtration efficiency, and ease of maintenance.
