I'm reaching out to inquire about your air purifiers as we are looking to make a significant purchase. Could you please provide details on your available models, pricing, and any bulk order discounts? Additionally, I'd appreciate information on lead times, warranty options, and shipping arrangements. We're aiming to finalize our decision soon, so your prompt response would be greatly appreciated. Looking forward to your reply!
